What do you understand by a search engine?

A search engine is a web-based software program that is developed to search and find information on the World Wide Web. It enables internet users to search the information via the World Wide Web (WWW). The user is required to enter keywords or phrases into the search engines and then search engine searches websites, web pages or documents containing similar keywords and presents a list of web pages with the same keywords in the search engine result pages.

How does a search engine work?
To understand, how a search engine works, we can divide the work of search engines into three different stages: crawling, indexing, and retrieval.

Digital Marketing – Is advertising delivered through digital channels. Channels such as social media, mobile applications, email, web applications, search engines, websites, or any new digital channel.

Google – Company behind the search engine giant Google.com. Founded in 1998, Google now controls approximately 80% of the search market. Google has also expanded to include many software services, both directly related to search, and targeted towards consumers outside of the search marketing industry like Google Chrome (a web browser), Google Fiber (internet service), Gmail (email client), and Google Drive (a file storing platform). Google is owned by the parent company Alphabet.

Google Adwords – Google’s online advertising service. This system allows advertisers to reach customers through their search and display networks. AdWords offers several cost models that vary by bidding strategy and company goals. Advertisers can bid on keywords that allow their ads to show in Google search results and on Google’s network of partner websites.

Google Chrome Security Warnings – In October 2017, Google made another step towards encouraging HTTPS/SSL Certificates for websites. Chrome users that visit sites without HTTPS are now shown a warning message that the site could be hazardous.

Google Fred Update – In March 2017, Google appeared to roll out a major update that penalized low-quality content. Google did not confirm this, except that they make algorithm changes a regular basis. Gary Illyes joked that these types of updates should be referred to as Fred and the name stuck.

Google Maps – The location and navigation service provided by Google. Using maps.google.com, users can search for stores, restaurants, businesses, and landmarks anywhere in the world. Google Maps is one of the most widely used navigation apps, providing GPS directions that update in real-time, according to traffic patterns and issues.

Google Partner Agency – An agency that is certified by Google for meeting certain requirements. To be a Google Partner, an agency must have an Adwords certified employee affiliated to the company profile, meet spend requirements, and Meet the performance requirement by delivering overall ad revenue and growth, and maintaining and growing the customer base.

Google My Business – The platform on which businesses can input information to appear in the search results, map packs, location searches, and more. Name, address, phone number, website link, hours of operation, reviews and more can all be managed through this tool. GMB is crucial to local SEO campaigns and is directly related to location-based searches.

Google Hummingbird – The industry nickname for one of the first major overhauls to the main Google search algorithm. In contrast to algorithm updates like Panda or Penguin, Hummingbird was intended to completely update the way Google interpreted user search queries. Previous to this update, Google results were mostly provided based on specific keyword matching within the user query. Now, a search for “Cheapest way to build birdhouse without using wood” will show results directly related to that query.

Google Medic – A major Google algorithm update in the summer of 2018 that primarily affected medical, fitness, health-related and “YMYL” websites. Many sites in those fields saw significant drops in rankings, though Google denies specifically targeting these industries. This update is sometimes referred to as the “Query Intent Update”.

Google Panda – A Google algorithm update focused on analyzing the quality of a website’s on-page content. Initially released February 2011, and updated periodically after this release, similar to Google Penguin. This update would determine if the content on site pages was related to queries it was being displayed for, and alter the site’s rankings accordingly. Sites with low-quality content saw significant ranking drops due to this algorithm update.

Google Mobile-First Index Rollout Update – In early 2018, Google announced that it was beginning to roll out its mobile-first updates. Mobile-first refers to the Google initiative that encourages developers to build sites with a mobile view focus. Mobile-first requires responsive websites that work on any smart device and are optimized for fast loading speeds. Sites that are not mobile-friendly will lose rankings or not be listed in mobile search results.
Google Mobile Speed Update – In July 2018, Google followed up on its announcement to use page speed as a ranking factor for mobile devices. This update is only supposed to affect the slowest mobile sites.

Google Penguin – A Google algorithm update focused on analyzing the quality of links pointing to a site, or more accurately, the overall quality of a site’s backlink profile. First announced in April 2012 and updated periodically after this release, similar to Google Panda. This algorithm targeted so-called “black-hat SEO” tactics that manipulated search rankings by creating links to sites in an unnatural manner. Google analyzes all of the pages which link to a specific site and determine whether the links are a benefit to users, or if they simply serve to manipulate search rankings and adjust the site’s standing accordingly. Google estimates that Penguin affects 3.1% of all searches in English, a relatively large number for one algorithm.

Google Pigeon – A Google algorithm update focused on providing locally relevant results to searchers. For example, searching for “SOHO coffee shop” will return results primarily centered around that neighborhood. In addition, Google can determine your location when you enter a search, and show you local businesses nearby your area even without localized keywords. This algorithm greatly influenced the potential for local businesses to appear in search results.

Google Algorithm – A mathematical programmatic system that determines where websites will appear on Google search result pages for any given number of queries. Sometimes also called the “Core” algorithm, though this is a less specific term. Google’s algorithm is constantly updated (approximately 500-600 times a year, or two times per day), which can have varying levels of impact on the rankings of websites across the world. Google’s actual algorithm is kept deliberately secret to prevent webmasters from manipulating the system for rankings, though Google does publically state their suggested “best practices” for appearing higher in search results.

Google Reviews – Reviews left using Google My Business platform. Reviews are on a 1-5 star scale and include a brief message written by the reviewer. Reviews can show up in the knowledge graph in Google searches and have been shown to positively correlate with SEO rankings.

Google Search Console (formerly Webmaster Tools) – Search Console is a free tool Google offers to webmasters. Within the tool are several areas that include data on how a site is performing in search. Search Console differs from Analytics – it does not measure traffic, it measures a site’s visibility on search pages, and indexability by Google crawler bots. Metrics Search Console measures are Click-Through Rate, Number of Indexed Pages, Number of Dead Links (AKA 404 pages), and more. (See also: Google Analytics, Click-through rate, Index, Crawler/Spider)

Google Tag Manager – GTM is a tool that is designed to manage JavaScript and HTML tags that are used for tracking and analytics on websites. It allows webmasters and SEOs to add snippets of code and tracking pixels, without having to modify the onsite script.

Gravity Forms – A WordPress plugin that adds a customizable contact form to a website. This plugin keeps track of all completed form submissions and allows for all of the fields on a form to be customized. Gravity Forms integrates with any third parties and is, therefore, the standard contact form plugin used on sites built by Geek Powered Studios.

Crawling: It is performed by software robots called web spiders or web crawlers. Each search engine has its web spiders to perform crawling. In this step, the spiders visit websites or web pages and read them and follow the links to other web pages of the site. Thus by crawling, they can find out what is published on the World Wide Web. Once the crawler visits a page, it makes a copy of that page and adds its URL to the index.

Indexing: It involves building an index after crawling all websites or web pages found on the World Wide Web. An index of the crawled sites is made based on the type and quality of the information provided by them and stored in huge storage facilities. It is like a book that contains a copy of each webpage crawled by the spider. Thus, it collects and organizes the information from all over the internet.

Retrieval: In this step, the search engine responds to the search queries made by the users by providing a list of websites with relevant answers or information in a particular order. It keeps the relevant websites, which offer unique and original information, on the top of the search engine result pages. So, whenever, a user performs an online search, the search engine searches its database for the websites or web pages with relevant information and makes a list of these sites based on their relevancy and presents this list to the users on the search engine result pages.

What is the long-tail keyword?
Ans. Long-tail keywords are phrases containing over 4+ words that make search results highly specific.
Keyword Phrase – A group of two or more words that are used to find information in a search engine. Sometimes, when searching for something, one single keyword does not provide the information you seek, where a keyword phrase allows you to string multiple words together to find better information.

What are the LSI keywords?
LSI keywords are words and phrases with a high degree of correlation to your target topic. Google’s algorithm uses them to help determine the content quality and relevance to the search term.

What are some techniques of Black Hat SEO?
Keyword Stuffing: The search engines study the keywords included in a webpage to index the webpage or a site. So, some people increase the keyword density in their web pages to get a higher ranking. Keywords should be 2 to 4 % of the total world count, increasing keyword density beyond this is known as black hat SEO as it is against the SEO guidelines of Google.

Cloaking: In this technique, the web pages are coded are in such a way that visitors see different content in a webpage and search engines see different content on the same webpage. Increasing ranking in this way is also against the guidelines of the search engine.

Doorway pages: These pages are rich in keywords and do not have quality content and relevant information. They redirect users to a different page to increase the ranking of that page. It is also against the guidelines of Google.

Hidden Text: It is the text that can be viewed by the search engine, but visitors cannot view it. It is used to include irrelevant keywords and hide text or links to increase the keyword density and improve the internal link structure.

Article Spinning: It refers to rewriting an article multiple times to produce its different copies in such a way that each copy looks different from other copies and is treated as a new article.

Duplicate Content: It is the content that is copied from one site and uploaded

Which are the most important areas to include your keyword for SEO purposes?
Page title, H1, Body text or content, Meta title, Meta description, Anchor links and Image Alt Tags are some of the most important areas where we can include our keywords for the SEO purpose.

What is a webmaster tool in SEO?
A webmaster is a free service by Google which provides free Indexing data, backlinks information, crawl errors, search queries, CTR, website malware errors and submits the XML sitemap. It is a collection of SEO tools that allow you to control your site in Google as well as allows Google to communicate with webmasters.

What do you mean by Spider?
Many search engines use programs called spiders to index websites. The spiders are also known as crawlers or robots. They act as automatic date searching tools that visit every site to find new or updated web pages and links.

What are Meta Tags?
Meta tags are the HTML tags that are used to provide information about the content of a webpage. They are the basic elements of SEO. Meta tags are incorporated in the “head” section of HTML, e.g.Meta tags are placed here.
The Meta tags are of three types. Each tag provides specific information about the content of the page. For example:

Title Tag: It is the most important of all the Meta tags. It tells search engines about the title of your webpage, and it is displayed in search engine listings above the URL of your webpage or website. For example:

Description Meta tag: The summary of your site or webpage is incorporated in this tag. It enables the search engine to display a brief description of your page in the SERPs. Through this tag, you tell users what your site is all about and what you are offering. For example:
Keywords Meta tag: In this tag, you place all of your main keywords and phrases that describe the content of your webpage.

Why is the title tag valuable?
A title tag is an HTML element that is used to specify the title of a page. It is displayed on search engine result pages as a clickable heading just above the URL and at the top of the browser.
In SEO, the title tag is significant. It is highly recommended to include a unique and relevant title that correctly describes the content of a webpage or a website. Thus, it tells the users and search engines about the nature or type of information contained in your webpage.

Does Google use the keyword Meta tags?
No, Google does not use the keyword meta tags in web search rankings. It is believed that Google ignores the meta tags keywords due to its misuse.
Reciprocal Link – Two websites linking to each other, typically for the express purpose of increasing both’s search engine ranking. These types of links are sometimes deemed manipulative by search engines, which can incur a penalty or devaluation against both sites.

What is cloaking?
Cloaking is a black hat SEO technique that enables you to create two different pages. One page is designed for the users, and the other is created for the search engine crawlers. It is used to present different information to the user than what is presented to the crawlers. Cloaking is against the guidelines of Google, as it provides users with different information than they expected. So, it should not be used to improve the SEO of your site.

What is the difference between SEO and SEM?
SEO: It is a process of increasing online visibility, organic (free) traffic or visitors to a website. It is all about optimizing your website to achieve higher rankings in the search result pages. It is a part of SEM, and it gives you only organic traffic.
Two types:
On-Page SEO: It deals with the optimization of a website for maximum visibility in the search engines.
Off-Page SEO: It deals with gaining natural backlinks from other websites.
SEM: It stands for search engine marketing. It involves purchasing space on the search engine result page. It goes beyond SEO and involves various methods that can get you more traffic like PPC advertising. It is a part of your overall internet marketing strategy. The traffic generated through SEM is considered the most important as it is targeted.
SEM includes both SEO and paid search. It generally makes use of paid searches such as pay per click (PPC) listings and advertisements. Search ad networks generally follow a pay-per-click (PPC) payment structure. It means you only pay when a visitor clicks on your advertisement.

What are the tools used in SEO?
Google webmaster tools: Google webmaster tool is a free SEO tool offered by Google. It is a set of SEO tools that allow you to control your website. It informs you if anything goes wrong with your website like crawling mistakes, plenty of 404 pages, malware issues, manual penalties, etc. In other words, Google communicates with webmasters through this tool. You also do not need to use most of the expensive SEO tools if you are using this tool.

Google Analytics: It is a freemium web analytics service offered by Google. It provides detailed statistics of the website traffic. It was introduced in November 2005 to track and report website traffic. It is a set of statistics and analytical tools that monitor the performance of your site. It tells you about your visitors and their activities, dwell-time metrics, search terms or incoming keywords and more.

Open site explorer: This tool provides stats such as overall link counts and the count of domains that are linked to a URL including the anchor text distribution.

Alexa: It is a ranking system that ranks websites by web traffic data. The lower the Alexa rank, the more will be the traffic.

Website grader: It is a free SEO tool that grades the websites on some key metrics such as security, mobile readiness, performance, and SEO.

Google Keyword Planner: This tool of Google comes with many features. It gives you an estimation of traffic for your target keywords and suggests keywords with high traffic. Thus, you can shortlist the relevant keywords from the list of keywords offered by this tool.

Plagiarism Checker: There are various tools to check the plagiarized content such as smallseotools.com, plagiarisma.net and more. Using these tools, you can avoid duplicate content and upload the unique or original content on your site.

Metadata – HTML snippets added to a webpage’s code that add contextual information for web crawlers and search engines. Search engines use metadata to help decide what information from a webpage to display in their results. Example meta tags include the date the page was published, the page title, author, and image descriptions.
Meta Keywords: A specific meta tag that displays the specific keywords addresses on a page. After meta keyword markup was abused on some websites, listed keywords no longer apply to how a page is categorized by google and other search engines.

Meta Description: One of the meta tags that give a description of the page in 160 characters. The meta description is an important aspect of a webpage because it is what appears in Google searches and other search engine results.

What are the limitations of the title and description tags?
The title tag should be between 66-70 characters as Google generally displays the first 50to 60 characters of the title tag. So, if your title is under 60 characters, there are more chances that your title is displayed properly. Similarly, the Meta description tag should be between 160-170 characters as the search engines tend to truncate descriptions longer than 160 characters.

What methods should you use to decrease the loading time of a website?
We should follow the following instructions to decrease the loading time of a website:
Optimize images: You can optimize images and decrease the file size without affecting the quality of that image. You can use the external picture tools to resize your images such as Photoshop, picresize.com and more. Furthermore, use fewer images (avoid them unless necessary).

Use browser caching: Caching involves temporary storage of web pages that helps reduce bandwidth and improve performance. When a visitor visits your site, the cached version is presented that saves the server’s time and loads pages faster. So, use browser caching to make the process easier and faster for your repeat visitors.

Use a content delivery network: It allows you to distribute your site across several servers in different geographical areas. When visitors request to visit your site, they will get the data from the server closest to them. The closer a server, the more quickly it loads.

Avoid self-hosted videos: Video files are usually large, so if you upload them to your web pages it can increase their

loading time. You can use other video services like Youtube, Vimeo, etc.

Use CSS sprites to reduce HTTP requests: It allows you to combine some images within a single image file by implementing CSS positioning of background. It helps you to save your server bandwidth and thus loading time of the webpage decreases gradually.

Which tool should be preferred between Webmaster and Analytics?
Webmaster tool should be preferred over Analytics tool because it includes almost all essential tools as well as some analytics data for the search engine optimization. But now due to the inclusion of webmaster data in Analytics, we would like to have access to Analytics.

When is inclusion applied in a search engine’s index?
If your website is banned by the search engines for using black hat practices and you have corrected the wrongdoings, you can apply for inclusion. So, it is a process in which you ask the search engine to re-index your site that was penalized for using black hat SEO techniques. Google, Yahoo, and other search engines offer tools where webmasters can submit their site for inclusion.

What is robot.txt?
Robots.txt is a text file that gives instructions to the search engine crawlers about the indexing of a webpage, domain, directory or a file of a website. It is generally used to tell spiders about the pages that you don’t want to be crawled. It is not mandatory for search engines, yet search engine spiders follow the instructions of the robots.txt.
The location of this file is very significant. It must be located in the main directory otherwise the spiders will not be able to find it as they do not search the whole site for a file named robots.txt. They only check the main directory for these files, and if they don’t find the files in the main directory, they assume that the site does not have any robots.txt file and index the whole site.

What is keyword proximity?
Keyword proximity refers to the distance between the keywords, i.e., it tells how close keywords are to each other in a phrase or body of the text. It is used to measure the distance between two keywords in the text. It is used by some search engines to measure the relevancy of a given page to the search request. It specifies that the closer the two keywords in a phrase or a search term, the more relevant will be the phrase. For example, see the keywords “Delhi Digital Photographer” in the search term “Delhi Photographer Ram Kumar specialized in digital photography.” The proximity between Delhi and Photographer is excellent, but between the “Photographer” and “digital” proximity is not good as there are four words between them. So, a search term’s keywords should be as close to each other as possible.

What is an URL?
URL stands for Uniform Resource Locator (URL). It is the web address of an online resource like a website, webpage or document on the internet. It tells the location and name of the resource as well as the protocol used to access it, i.e., it locates an existing resource on the internet. A URL may contain as many as six parts, and cannot have less than two parts. For example, http://www.example.com, in this URL we have two parts: a protocol (Http) and a domain (www.example.com).

A URL for HTTP or HTTPS generally comprises three or four components, such as:
Protocol: It is used to access the resource on the internet. It can be HTTP, without SSL or HTTPS with SSL. It is connected to the domain name, and the domain name is further connected to the file path.

Domain name: It is a unique name that identifies a website on the internet. For example, “javatpoint.com”. It always includes a top-level domain (TLD) which is “.com” in this example.

Port: It is a port number, which is usually not visible in a URL, but it is always required. When visible, it comes after the TLD, separated by a colon.

Path: It is a file or directory on the web server, e.g. “/SEO-interview-question” in the URL https://www.javatpoint.com/seo-interview-questionsis a path.

HTTP – Stands for Hypertext Transfer Protocol. HTTP is the protocol used by the world wide web to define how data is formatted and transmitted, and what actions web browsers and web servers should take to respond to a command. When you enter a website into your web browser and press enter, this sends an HTTP command to a web server, which tells the server to fetch and send the data for that website to your browser.

HTTPS – Stands for Hypertext Transfer Protocol Secure. Is a secured version of HTTP, which is used to define how data is formatted and transmitted across the web. HTTPS has an advantage over HTTP in that the data sent when fetching a webpage is encrypted, adding a layer of security so that third parties can’t gather data about the webpage when the data is sent from the server to the browser. HARO emails are sent out, listing different stories that reporters need sources for. Used as a marketing strategy to gain PR and link opportunities.

Hashtag – a phrase beginning with the symbol “#” used in social media as a way for tagging content for users to find. Adding hashtags to a post allows users to find that post when searching for that topic. This can be used for finding users looking for broad topics on social media, as well as niche, detailed topics.

Header – Can refer to either the top portion of a webpage that typically contains the logo and menu, or the section of HTML in a website’s code that contains important information about the site.

Header Code – On a website, a certain code is placed in the universal header section so that it can be accessible across all pages of the website. Typically in the header code, you’ll find things like Schema Markup, Analytics Code, Adwords Code, and other tools used for tracking data across a website. These are placed in the header code so that they can be rendered and start tracking information as the site loads.

Header Tags (h1, h2, h3, etc) – Header tags are used in HTML for categorizing text headings on a web page. They are, in essence, the titles and major topics of a web page and help indicate to readers and search engines what the page is about. Header tags use a cascading format where a page should generally have only one H1 (main title) but beneath can be multiple H2s (subtitles) and every H2 can have H3s beneath (sub-sub titles) and so on.
H1 is typically used only once on a webpage and is used to display the most important title.
H2 is used to display the major subtopics of a certain webpage
H3 is used to display the major subtopics underneath an H2 tag.

Hreflang Tag – A code in the Html of a website that tells search engines like Google which spoken language a web page is using. These are especially useful for websites that have versions of pages in multiple languages, as they help Google understand which pages are related and which should be shown to specific audiences.

IP Address – An IP (Internet Protocol) address is a unique number that identifies a device using the internet to communicate over a network. Each device has a unique IP address and can be used to locate and differentiate that device from all other devices when using the internet. You can find your public IP address by going to Google and searching “what is my IP address.”

What is an internal link?
An internal link is a URL link placed on your website that points to your other webpage. It is different from an external link which leads to another website. Internal links are very useful regarding SEO as they:

Provide site structure: The internal links of a website helps search engines to crawl and index your website. Search engine crawlers or robots use internal links to evaluate your website and are better informed while ranking your website on search engine result pages.

Enhance user experience: The internal links in product pages, blog posts, contact us forms, etc., enhance users’ website experience. Furthermore, these links can be used to take prospects to your core pages to convert them into customers.

Minimize bounce rate: The internal links keep visitors on your website for longer and thus helps reduce bounce rate and increases the likelihood of them buying your products or services.

Why are backlinks important?
The backlinks are an indication of the popularity of a website. They are important for SEO as most of the search engines like Google give more value to websites that have a large number of quality backlinks, i.e., a site with more backlinks is considered more relevant than a site with fewer backlinks.
The backlinks should be relevant which means they should come from the sites that have content related to your site or pages otherwise the links if they are coming from sites that have different content, will be treated as irrelevant backlinks by the Search Engine. For example, there is a website about how to rescue orphaned dogs, and it receives a backlink from a website about dog care essentials then this would be a relevant backlink in a search engine assessment than a like from site about automobiles.

What is the difference between an inbound link and an outbound link in SEO?
An inbound link, which is also known as a backlink, is the incoming link to your site from an external source. It comes from an external site to your site. Whereas, an outbound link is a link that starts from your site and points to another website. For example, if xyz.com links to your domain, this link from xyz.com is an inbound or backlink for your domain. However, it is an outbound link for xyz.com.

What is link popularity?
Link popularity refers to the number of backlinks that point towards a website. The backlinks can be of two types: internal and external links. The links to a website from its pages are called internal links and the links from outside sources or other websites are called external links.

The high link popularity indicates that more people are connected to your site, and it has relevant information. Most of the search engines use link popularity in their algorithm while ranking websites in the SERPs. For example, if two websites have the same level of SEO, the site with higher link popularity will be higher than another site by the search engine.

What is a web page?
A web page is what you see on the screen of a computer or mobile when you type a web address or click on a link or enter a query in a search engine like Google, Bing, etc. A web page typically contains information that may include text, graphics, images, animation, sound, video, etc.

Dofollow – A phrase that denotes a hyperlink absent of a “no-follow” tag. By default, a hyperlink is a do-follow link until a “no follow” piece of code is added to it. Dofollow links pass SEO equity to the destination URL, while “no-follow” links do not.
Referral – A medium denoted in Google Analytics that represents a website visit that came from another website (as opposed to coming from a Google search, for example). When users click on a link to another, external webpage, they are said to have been “referred” there.

Remarketing – Also known as retargeting, a type of paid ad that allows advertisers to show ads to customers who have already visited their site. Once a user visits a site, a small piece of data called a “cookie” will be stored in the user’s browser. When the user then visits other sites, this cookie can allow remarketing ads to be shown. Remarketing allows advertisers to “follow” users around in attempts to get the user back to the original site.
Responsive websites – that are deemed mobile-friendly are prioritized to show up in Google searches on mobile devices.

Responsive Web Design – A philosophy of creating a website that allows all of the content to show correctly regardless of screen size or device. Your website will “respond” to the size of the screen each user has, shrinking and reorganizing on smaller screens, and expanding to fill appropriately on large ones.

ROI – Stands for Return On Investment. In order for a business to receive a positive ROI, they must earn more money using marketing channels than they are spending on the marketing itself.

RSS – Stands for Really Simple Syndication. It is a way for users to keep track of updates to multiple websites (news sites, blogs, and more) in one place, as opposed to having to manually check in on every single site individually. An RSS Feed is a place where all updates are tracked together, in an easily viewable format.

What are the organic results?
Organic results refer to the listings of web pages on the SERPs that appear because of organic SEO such as relevance to the search term or keywords and free white hat SEO techniques. They are also known as free or natural results. Search engine marketing (SEM) is not involved in producing organic results. So, organic results are the natural way of getting a top ranking in SERP. The main purpose of SEO is to get a higher ranking for a web page in organic results of search engines.

What are the paid results?
Paid search results are the sponsored ads or links that appear on the SERPs. They are part of Search Engine Marketing in which you have to pay to place your websites or ads on the top of the result pages.

What is a 404 error?
A 404 error is an HTTP response status code which indicates that the requested page could not be found on the server. This error is generally displayed in the internet browser window just like web pages.

What are the causes of HTTP 404 errors?
HTTP 404 error is technically a client-side error which means it is your mistake, i.e., the requested page is not present on your website. If you had maintained that page in your site, it would have been indexed by the crawler and thus would have been present in the server. Furthermore, you also receive this error, when you mistype a URL or when a webpage or resource is moved without redirecting the old URL to the new one. So, whenever you move your webpage redirect the old URL to the new URL to avoid this error as it may affect the SEO of your site.

Thus, it helps you take the necessary steps to improve the SEO of your site and online marketing strategies. Anyone with a Google account can use this tool.
The reports generated by Google Analytics can be divided into four different types of analysis which are as follows;
Audience Analysis
  Acquisition Analysis

You can find the location and language of visitors.
  You can identify new visitors and returning visitors.
  You can identify browsers, operating system and the network of visitors.

You can generate a content drill down a report which will give you a crucial perspective on site usage and information about landing and exit pages.
  You can measure page timings and user timings which will suggest the ideal site speed.
  You will know how the users move across your site, what they normally search before arriving at a landing page.

Conversion Analysis: Website conversion analysis is an important part of the SEO process. Every website has a particular goal such as generating leads, selling products or services, to increase targeted traffic. When the goal is achieved, it is known as conversion. Some major benefits of this analysis are as follow;
It enables you to track conversions such as download, check out, buy, etc.

  You can generate multi-channel funnel reports from conversion paths.
  You can identify which module, platform, and strategy are best for your business.

Visits – An old term in Google Analytics which was recently changed to “sessions”.

Visitors – A metric in Google Analytics that quantifies a user of a website over a particular period of time. Visitors are often broken down between “new visitors” who are browsing for the first time in the allotted time period, or “returning visitors” who have already browsed at least once in the given time frame.

Campaign – A series of advertising messages that share a theme, and market a product or service. In the context of digital marketing, campaigns can be run through search and display network advertising platforms (i.e. Google, Bing), social media, email, or other online platforms. Campaigns can also refer to a comprehensive digital marketing strategy or project.

Click-Through-Rate – A metric showing how often people click on an ad or search result after they see it. It can be calculated by dividing the number of clicks, by the number of impressions (how many times the ad or search result was seen). This ratio can be useful when determining whether the messaging matches what the consumer is searching for and if it resonates with them. A higher click-through-rate means more engagement, which generally leads to more quality conversions.

Code – The languages used to build a website. The most commonly used languages in web design are HTML, CSS, JS, and PHP.

Canonical (rel=canonical) – A piece of code that is added into the Html head of a webpage to indicate to Google whether a piece of content is original or duplicated from somewhere else. Original content should canonical to itself, and content taken from other places should point the canonical to the original source URL. Canonicals can also be used to avoid duplicate content issues within a website.

Contact Form – A section on a website with fillable fields that visitors use to contact the website owner. Most commonly used to collect names, phone numbers, and email addresses of potential customers. Contact forms are fast becoming a preferred method for reaching out to a business.

Content – Any form of online media that can be read, watched, or provides an interactive experience. Content commonly refers to written materials, but also includes images and videos.

Conversion – The completion of a predefined goal. This is often used to track the number of site visitors that have been “converted” into paying customers, though sales are not always chosen as the metric. Other common goals are newsletter subscriptions and content downloads from the website.

CPA (Cost Per Acquisition) – A metric in paid advertising platforms that measures how much money is spent in order to acquire a new lead or customer. It can be calculated by dividing the total spend by the number of conversions, for a given period of time. For example, if in a month a PPC account spends $1000 dollars and gets 10 conversions (leads), then the cost per acquisition is $100.

Conversion Rate – The rate at which visitors to a website complete the predefined goal. It is calculated by dividing the number of goal achievements by the total number of visitors. For example, if 100 people visit a website and 10 of them complete the conversion goal (like filling out a contact form) then the conversion rate is 10%.

CPC (Cost Per Click) – The amount of money spent for a click on an ad in a Pay-Per-Click campaign. In the Adwords platform, each keyword will have an estimated click cost, but the prices change in real-time as advertisers bid against each other for each keyword. Average CPCs can range from less than $1 dollar for longtail or low-competition keywords, to upwards of $100 per click for competitive terms, primarily in legal, insurance, and water damage restoration industries.

CPM – Stands for “Cost Per Thousand” (M is the roman numeral for 1,000). This is the amount an advertiser pays for 1,000 impressions of their ad. For example, if a publisher charges $10 CPM, and your ad shows 2000 times, you will pay $20 for the campaign ($10 x 1000 impressions) x 2. Measuring ad success with CPM is most common in awareness campaigns, where impressions are more important than conversions or clicks.

CSS – Stands for “Cascading Style Sheets”. CSS is a document of code that tells the website’s HTML how it should appear on the screen. CSS is a time-saving document for web designers, as they can style batched-sections of HTML code, rather than styling individual lines of code one-at-a-time.

CRO (Conversion Rate Optimization) – A branch of digital marketing that aims to improve the conversion rate of web pages, thus making the pages more profitable. Conversion rate optimization combines psychology with marketing and web design in order to influence the behavior of the web page visitor. CRO uses a type of testing called “A/B split testing” to determine which version of a page (version A or version B) is more successful.

CTR (Click Through Rate) – the ratio of how many times an advertisement was clicked on, versus how many times it was shown. It is calculated by dividing the ad’s clicks by the ad’s impressions. For example, if an ad is shown to 100 people, and 10 of them click the ad, then it has a click-through rate of 10% (10 clicks / 100 impressions = 10%)

CTA (Call to Action) – An element on a web page used to guide visitors towards a specific action or conversion. A CTA can be a clickable button, an image, or standard text. They typically use imperative verb phrases like: “call today” or “buy now”.

How do you know which pages are indexed by Google?

2. The second method involves a manual search on Google. In this method, you are required to type on Google search bar site:domainname.com. The indexed pages would reflect on the SERP.

What is Google Page Rank?
PageRank is one of the important ranking factors that Google uses to rank the web pages on the basis of quality and quantity of links to the web pages.

Google generally imposes the penalty in three different ways: Bans, Rank Demotion, and Temporary Rank Change.

What is HTTPS/SSL Update?
HTTPS, which stands for Hypertext Transfer Protocol Secure), is a protocol for secure communication on the World Wide Web. It uses SSL (Secure Sockets Layer) to add an extra layer of security to the standard HTTP connection, i.e., it is a secure version of HTTP. It encrypts all data or communication between the server and the browser.

The websites which use HTTP protocol, the data is transmitted between the site server and the browser as plain text, so anyone who intercepts your connection can read this data. Earlier, only the websites that handle sensitive data like credit card information were using it, but now almost all sites prefer HTTPS over HTTP. An HTTPS connection provides the following benefits:
Website Authentication
  Data Integrity
  Data Encryption

What is keyword density?
Keyword density is the percentage of times a keyword or phrase appears on a web page compared to the total number of words on the page. For example, if a keyword appears four times in an article of 100 words, the keyword density would be 4%. It is also known as keyword frequency as it talks about the frequency of occurrence of a keyword in a page. There is no ideal or exact keyword density for better ranking. However, the keyword density of 2 to 4 % is considered suitable for SEO.

What is keyword stuffing?
Keyword stuffing refers to increasing the keyword density beyond a certain level to achieve a higher ranking in the SERPs. As we know, web crawlers analyze keywords to index the web pages, so some SEO practitioners exploit this feature of the search engine by increasing the keywords on a page. This way of improving the ranking is against the guidelines of Google, so it is considered a black hat SEO technique, and it should be avoided.

What is article spinning?

What is the Disavow tool?
The Disavow tool is a part of Google Search Console that was introduced in October 2012. It enables you to discount the value of a backlink in order to prevent link-based penalties. It also protects the site from bad links that may harm the website’s reputation.

Using this tool, you can tell Google that you don’t want certain links to be considered to rank websites. Some sites who buy links may suffer the penalty if they don’t get these links removed using the Disavow tool. The low-quality backlinks, which you don’t control, may harm your site’s ranking. You can ask Google not to consider them when crawling and indexing your site.

What is Fetch as Google?

How would you maximize the frequency of crawling of your website by search engines?

Update your pages regularly: You must have to frequently add new, original and quality content on the website for this.

Server’s Uptime: If a site is down for a long time, the crawlers reduce the frequency of crawling for that site. So, host your website on a reliable server with good uptime.

Create Sitemaps: You can submit a sitemap of your website to make your site discover quickly by search engine spiders. In WordPress, you can generate a dynamic sitemap with Google XML sitemap plugin and submit it to the Webmaster tool.

Avoid Duplicate Content: The copied content tends to reduce the crawling rate as using plagiarized material is against the guidelines of Google. So, always provide new and unique content.

Reduce site’s loading time: The loading time should be less as the crawl has a limited time and if it spends too much time on big images included in the content, it will have no or less time to visit other pages.

Build more links: You can build more backlinks from regularly crawled sites. Interlinking helps search engines to crawl deep pages of your site. So, whenever, you create a new page add a link in your old related pages to your new page.
Use optimized images: The crawlers cannot read images directly so always use alt tags to provide a description that search engine crawlers can read and index.

What is referral traffic?
The referral traffic refers to the visitors that come to your site from the direct links on other websites rather than from the search engine. In simple words, the visits to your domain directly from other domains are called referral traffic. For example, a site that likes your page may post a link recommending your page. The visitor on this site may click on this link and visit your site.
You can also increase referral traffic by leaving links on other blogs, forums, etc. when you put a hyperlink of your page on other websites like forums users will click and visit your webpage. Google tracks such visits as referral visits or traffic. So, it is Google’s way of reporting visits that come to your site from sources outside of search engines.

Bread Crumbs – Links at the top of a web page or in a search result, that better help the user navigate the site. Onsite links often appear near the web page’s title and look something like this: Home > Services > Specific Service. Breadcrumbs can also be found in search results through specific schema markups. These help users find related pages from the search result listing.

What is keyword stemming?
Keyword stemming is the process of finding the root word of a search query and then creating new keywords by adding prefixes, suffixes and pluralizing the root word. For example, a query “Searcher” can be broken down to the word “search” and then more words can be created by adding prefixes, suffixes or pluralizing this root word, such as research, searcher, searchers, searching, searchable, etc.


What is LSI?
LSI stands for Latent Semantic Indexing. It is a part of Google’s algorithm which enables the search engine to understand the content of a page and the intent of the search queries. It identifies related words in content to better classify web pages and thus to deliver more relevant and accurate search results. It can understand synonyms and the relationship between words and thus can interpret web pages more deeply to provide relevant information to users. For example, if someone searches with a keyword “CAR,” it will show related things such as car models, car auctions, car race, car companies and more. See the image:


What is Canonical URL?

The basic idea being that if “website A” has incoming backlinks from other strong/relevant websites (websites B, C, and D), the links are votes of trust for website A. Website A will then gain authority from B, C, and D through those backlinks, which generally results in better rankings and a source of potential referral traffic.
