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 the similar keywords and presents a list of web pages with same keywords in the search engine result pages.

Furthermore, the links also contain the title and a short description of their web pages. Furthermore, SERP not only provides the list of search results, but it may also include advertisements.


11) 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.

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.

SEO Interview Questions

The web spider generally starts crawling with heavily used servers and popular web pages. It follows the route determined by the link structure and finds new interconnected documents through new links. It also revisits the previous sites to check for the changes or updates in the web pages. If changes are found, it makes a copy of the changes to update 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 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.

SEO Interview Questions

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 make a list of these sites based on their relevancy and present this list to the users on the search engine result pages.

12) What is the usage of an anchor tag in SEO?

The anchor tag is used to make click-able text written on a hyperlink, i.e., it is a clickable text in a hyperlink. It enhances the user experience as it takes the users directly to a specific area of a webpage. They are not required to scroll down the information to find a particular section. So, it is a way to improve navigation.

It also enables webmasters to keep things in order as there is no need of creating different web pages or splitting up a document. Google also sends users to a specific part of your page using this tag. You can attach anchor tag to a word or a phrase. It takes the reader down to a different section of the page instead of another page. When you use this tag, you create a unique URL on the same page.


13) 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 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 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 to another site. It is known as plagiarism.

14) Which type of website is good for SEO purpose?

Spiders follow hyperlinks and gather textual and meta information for the search engine databases. They collect as much information as they can before relaying to the server of the search engine.

Spiders may also rate the content being indexed to help the search engine determine relevancy levels to a search. They are called spiders as they visit many sites simultaneously, i.e. their legs keep spanning a large area of the web. All search engines use spiders to revise and build their indexes.


18) 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. <head>Meta tags are placed here</head>.

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 your webpage, and it is displayed in search engine listings above the URL of your webpage or website. For example: <title>Title text</title>
  • 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: <meta name="description" content = "your site's summary"/>
  • Keywords Meta tag: In this tag, you place all of your main keywords and phrases that describe the content of your webpage. For example: <meta name="keywords" content="keywords"/>

19) 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.

An ideal title should be between 50 and 60 characters long. You can also place your primary keywords at the start of your title and put the least important keywords at the end. It is the first thing that a search engine analyzes before ranking your webpage.


20) 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 their misuse.


21) 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.

SEO Interview Questions

Some Examples of Cloaking:

  • Presenting a page of HTML text to search engines and showing a page of images or flash to visitors
  • Including text or keywords into a page only when it is requested by the search engine, not by a human visitor

SEO: It is a process of increasing the 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 the 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 pay-per-click (PPC) payment structure. It means you only pay when a visitor clicks on your advertisement.

25) What are the limitations of the title and description tags?

The title tag should be between 66-70 characters as the 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.


26) 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 the Photoshop, picresize.com and more. Furthermore, use fewer images (avoid them unless necessary).
  • Use browser caching: Caching involves temporary storages 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 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 request: 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.

27) 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.


28) What is the main usage of search engine spiders?

A spider is a program used by search engines to index websites. It is also called a crawler or search engine robot. The main usage of search engine spiders is to index sites. It visits the websites and read their pages and creates entries for the search engine index. They act as data searching tools that visit websites to find new or updated content or pages and links.

Spiders do not monitor sites for unethical activities. They are called spiders as they visit many sites simultaneously, i.e., they keep spanning a large area of the web. All search engines use spiders to build and update their indexes.


29) When is reinclusion 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 reinclusion. 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 reinclusion.


30) 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.


31) 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 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.


32) 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 a 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.

So these domain extensions are reserved for countries. See the image given below:

37) What is an internal link?

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

38) 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.


39) 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, 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. See the image given below:

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.

SEO Interview Questions

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 its 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.

Indexing starts after crawling. It is a process of building an index by adding URLs of web pages crawled by the crawlers. An index is a place where all the data that has been crawled is stored, i.e., it is like a huge book with a copy of each page that is crawled. Whenever users enter search queries, it is the index that provides the results for search queries within seconds. Without an index, it won't be possible for a search engine to render search results so fast.

So, the index is made of URLs of different web pages visited by the crawler. The information contained in the web pages is provided by the search engines to users for their queries. If a page is not added to the index, it can't be viewed by the users.


44) What is the World Wide Web?

The World Wide Web is a like a huge book whose pages are located on multiple servers present throughout the world. These web pages contain information and are connected by links called "hypertext."

107) 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 sitemap of your website to make your site discover quickly by search engine spiders. In WordPress, you can generate dynamic sitemap with Google XML sitemap plugin and submit it to 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.

108) 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 a Google's way of reporting visits that come to your site from sources outside of search engine.


109) 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.

Similarly, you can add the prefix "en" to "large" to make it "enlarge" and add a suffix "ful" to "power" to make it "powerful." This practice allows you to expand your keyword list and thus helps get more traffic.


110) What is LSI?

LSI stands for Latent Semantic Indexing. It is a part of the 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:
