5. What is a search engine?
A search engine is a software system, which searches the world wide web for relevant information on a particular query raised by a user on the Internet.
6. Can you name a few search engines other than Google?
This is a popular SEO interview question. Here are a few of them:
7. What does WWW stand for?
WWW stands for the World Wide Web. It is a collection of websites stored in web servers, which are connected to local computers.
8. What do you know about web crawling?
Web crawling is the process where a web crawler (spiderbot/spider/crawler), an internet bot, browses the World Wide Web for web indexing. It uses hyperlinks to visit pages and copies them for processing and indexing by the search engine so that users on the Internet can search more quickly and efficiently.
9. Do you know about Googlebot?
Googlebot is Google’s web crawler. It finds, crawls, and indexes web pages.
10. What is search engine submission?
Search engine submission is the process of submitting your website to search engines to ensure that it gets crawled and indexed. Even though search engines are smart enough to find your website and index it easily, it is advisable to follow through with the search engine submission as you will get the opportunity to submit some useful information about your website from your end, and the search engines will alert you if potential errors are there on your site.
11. What is SERP?
SERP stands for search engine results page. This is the page where users see all the results of their queries on search engines.
12. Can you explain the difference between organic and paid results?
Both organic and paid results are types of search results on SERP shown on the basis of quality and relevance to the user query. Organic results are not paid to show up on SERP. It is very hard to rank high organically, and it requires SEO.
Paid results require bidding on keywords, and based on the Max CPC (cost per click) and quality score, they are positioned above the organic search results on SERP, and these are paid advertisements. The more you score, the less money you need to pay.
13. What are on-page SEO and off-page SEO?
On-page SEO is used to ensure that the website performance is improving and better by optimizing the meta tags and descriptions, page title, URL structure, keyword density, body tags, internal linking, images, etc.
Off-page SEO involves activities such as guest blogging, reverse guest blogging, press releases, social networking, etc. These are done away from the website to promote and increase the visibility of the same.
14. Have you heard of Google Sandbox?
While the existence of Google Sandbox has long been a subject of discussion, Google has not addressed the matter directly. It is theorized that new websites go through a probation period before they show up on SERPs. It is also believed that two important factors cause this filter to come to play—the active age of a domain and the keyword competitiveness. If the search frequency is higher for the keyword used, it is most likely that the filter will be put into effect for anti-spam purposes.
15. What is a domain name?
On the Internet, a domain name is an address where the Internet users can access your website, and it includes web addresses, email addresses, and the addresses of the Internet protocols. It is basically a shortcut to the server that hosts your website.
Without a domain name, one would have to enter the full IP address to visit a website. IP addresses are numerical labels and not very convenient for regular use.
A domain name has two main elements:
- The website’s name (g., Intellipaat)
- The domain name extension (e.g., .com)
16. What is a URL?
URL stands for Uniform Resource Locator. It is the complete address of a web page or a document on www. A URL contains the following parts:
- Protocol: A method used to process the URL (https, http, etc.)
- Domain: The domain name
- Path/File: The exact location of a page, file, other assets, etc.
- Query string: Parameters for dynamic data
- Hash: A specific section of a web page
17. What are SEO-friendly URLs?
URLs that are easily understandable by both search engines and users are SEO-friendly URLs. They will typically include keywords, and they are mostly self-explanatory and future proof so that they will not become obsolete over the years).
18. What is web hosting?
Web hosting is the www equivalent of buying a property. Web hosting companies will provide you with space to build your website. The server will have to be connected to the Internet for this hosting purpose.
19. What is DA?
Here is another commonly asked SEO interview question. DA or domain authority (a metric developed by Moz) is a search engine ranking score, which ranges from 0 to 100. The score predicts how well a website will rank on SERP. The higher your DA, the better chances you have at ranking higher.
20. Explain the difference between DA and PA.
While DA (domain authority) explains the authority of your entire website, PA (page authority) describes the authority of a specific page based on quality backlinks, social sharing, etc. The DA requires more time and effort than PA, but the former is more worthwhile in the long run. However, both are mutually beneficial.
21. What is TLD?
Top-level domain (TLD) is the final extension of an Internet address, for example, .com, .net, .org, .co.in, etc.
22. What is ccTLD?
In SEO, ccTLD, also known as the country code top-level domain, is a domain extension reserved for a country and has two characters. Here are a few examples for ccTLD: .it for Italy and .in for India.
23. What is PBN?

This SEO interview question will be asked to gauge your expertise. So, here are a few popular SEO tools:
- Google Search Console
- Google Analytics
- Sprout Social
26. Distinguish between a dofollow link and a nofollow link.
All hyperlinks are dofollow links by default unless specified as nofollow links. When search engine crawlers find a link, they crawl the page and pass the link juice as a vote of quality. The dofollow links from high-authority sites will help a site rank better in SERP by being quality backlinks.
Nofollow links are coded in a way that search engines do not crawl them or count them as votes of quality. You can use this when you want to link third-party sites on your website without passing the authority to those sites.
This is another popular SEO interview question, so make sure that you get the idea here.
27. What is SEO writing?
The usage of keywords and keyphrases within a website’s content is known as SEO writing. This helps increase the organic visibility of the website on the SERP.
28. Explain keywords.
Keywords are words or phrases users on the Internet use to find relevant results to their queries. They are also known as search queries. Figuring out potential keywords and using them in your website content can help you get a better ranking by search engines.
29. What is keyword frequency?
The number of times a particular keyword appears in a web page content is called keyword frequency. While the appropriate keyword frequency can optimize your website, using them excessively can quickly become a case of keyword stuffing.
30. What is keyword difficulty?
Keyword difficulty gives the measure of how difficult it is to get ranked for a particular keyword based on its high usage.
31. What is keyword proximity?
The distance or proximity between two keywords within a body of text on a web page is called keyword proximity. If the keywords are closer to each other in a phrase, the phrase will carry more weight.
32. What is keyword density?
Keyword density is the ratio or percentage of keywords used on a specific page. Around 3 to 4 percent is considered best practice.
33. What is keyword stuffing?
Keyword stuffing is considered to be a form of the black-hat SEO method. Increasing the keyword frequency to rank for specific keywords is generally frowned upon and could get your website penalized.
34. What is keyword stemming?
Google algorithm’s ability to identify different word forms on the basis of a particular word in a search query is called keyword stemming. This is done by adding prefixes, suffixes, pluralization, etc.
35. What is keyword prominence?
Keyword prominence shows the prominent placement (on the header, in the opening paragraph, at the start of a sentence, in meta tags, etc.) of keywords within a web page.
36. How many keywords should you use on a page?
It is good to have three primary keywords and some secondary keywords, but it shouldn’t look unnatural within the content, and the number of keywords to be used depends on the content length, page flow, keyword difficulty, etc.
37. What are long-tail keywords?
Keywords can be made into a more specific combination of several words. These are called long-tail keywords. Long-tail keywords can be very specific and, hence, can be good for attracting quality traffic from people who are interested in that specific search query, and they are more likely to transform this kind of traffic into conversions.
38. What is NAP?
NAP (name, address, phone number) helps search engines to identify the list of businesses to be displayed for location-based searches.
39. Define the bounce rate.
Get ready to face this important SEO interview question. The bounce rate is the percentage of visitors who exit the website from the landing page without visiting any other pages or without any activity. It is the ratio of a single-page session to all sessions on a website.
40. What are header tags?
HTML header tags are used to highlight the headings (h1 level) and the subheadings (h2–h6 levels) within the content of a web page. These tags are also called header tags or heading tags. If you skip from h1 to h3, the hierarchy will be broken, and it is not advisable for on-page SEO. Every page should possess only one h1 tag unless it is using HTML5, which allows for more.
41. What are meta titles and meta descriptions?
Meta titles (page titles) and meta descriptions are two different pieces of the HTML code, which are important when you are creating a web page. Much like the back-cover blurb of a book, these elements will tell users the title of the page they have landed on and will give them the summary of that page when it shows up on SERPs. This gives the users an idea of what your page is all about and whether it will be relevant for them to visit your website.
Moreover, web browsers use the meta titles in the browser bars so that it is easy to distinguish between different tabs of different pages if the users have opened multiple tabs in a session. The page titles are also used when people bookmark a web page for future reference.
42. What are internal links?
Internal links are hyperlinks that connect one web page to another web page in the same domain.
A well-planned internal linking structure can help users navigate the website without any confusion. It is a good practice to keep every important page within two–three clicks from the home page.
43. What are inbound links and outbound links?
Inbound links are links coming from another domain to your domain.
Outbound links are links going out from your domain to another domain.
Keeping a few outbound links to high-authority sites may be helpful, but excessive outbound links could hurt your SEO. So, you need to make sure to use nofollow links to avoid passing on the link juice.
44. What are backlinks?
Inbound links are also known as backlinks and are links coming from another domain to your domain.
45. What are anchor texts?
Anchor texts are used by search engines to understand the context of the web page to which it is linking. The clickable text in a hyperlink is called an anchor text. See the below example:
Check out Intellipaat’s SEO Course to have a deeper understanding of Search Engine Optimization.
46. What is robots.txt?
Robots.txt is a text file that instructs web crawlers about the pages on your site to crawl or not to crawl.
47. Explain the robots meta tag.
Robots meta tags (or robots meta directives) provide a granular approach on how to crawl and index a page’s content, for example, FOLLOW, NOFOLLOW, INDEX & NOINDEX, etc.
48. What is 301 redirect?
301 redirect helps redirect users and search engines from an old URL to a new one. 301 redirect passes most of the link juice from the old page to the new page.
49. What is Google Search Console or the Webmaster tool?
Google Search Console (previously known as Webmaster Tool) is a free service by Google that allows users to monitor the health and visibility of their websites. It offers the following insights:
- A confirmation that Google can find and crawl a site
- Troubleshooting indexing issues
- Re-indexing the fresh or updated content
- Showing the backlinks to the site
- Fixing problems in mobile usability, AMP, and other search features
- Monitoring Google Search traffic data for the site: How often the site appears on SERP, which specific search queries show the site, how often users click through for those search queries, etc.
- Alerts and notifications about spam, indexing problems, or other issues
50. What is image alt text?
A search engine cannot understand an image or what it is about. So, to give it an idea, the image alt text helps. It is an HTML attribute. If for some reason, the image is unable to be displayed on a browser, one can read the alt tags and understand what the image is about. It even optimizes the image for image searches and can be a Google ranking factor as well.
51. What is forum posting?
Forum posting is one of the off-page SEO techniques. You can join a forum and create a thread, or interact on an existing one, and engage with other users to have online discussions about topics. This is a good way to backlink to your site.
52. What is referral traffic?
Referral traffic is the visits that you get from uncrawlable websites like getting traffic from a link within an email or social media.
53. What is PPC?
This is again a common SEO interview question. Pay-per-click or PPC is an advertising model in which an advertiser pays the publisher when the ad is clicked. This helps drive traffic to your website, and you only pay when users click on your ad.
54. What is CTR?
Click-through rate or CTR is the ratio of users who click on a specific link to the number of total users who view it on a web page or other medium. This is yet another popular SEO interview question.
55. What is EMD?
EMD stands for the exact match domain and is a domain name that includes the search phrase, for example, buyflipphones.com. It is just an example and not an existing domain name, but you get the point.
