From past few years the concept of SEO had taken over almost all the tech and marketing grads to another level, they are not just enjoying to be part of this trend but also experiencing the immense pressure to maintain their decorum, to sustain in highly competitive tech and digital world. Today, where digitization had become the key to new world, so does the SEO is.

Top 100 SEO Interview Questions

100 seo interview questions

So let’s begin with SEO Interview Questions.

Interviewers usually in this field begin with the hard-hitting question first because they want to see the applicant’s captive and analytical skills in terms of Search Engine Optimization. The first question will began with some history type of things

1) Tell me something about SEO history and Birth?

As I said they will check your ability in beginning so this is the classical example of that question. Do you think this is easy to answer? Than you might be wrong, if you do not believe just search out the history of SEO. Everywhere, you will find the stanza where they say “SEO has obscure etiology of its birth”. So how you can answer this

Answer- Well, the question seems very interesting as like the concept of SEO is but as far as my knowledge is concern there is a big debate on its birth and history, it has obscure etiology of its birth. But I will try to answer because the logic behind the history is until and unless the Search Engine is born the concept of SEO can’t be born. So we can say Search Engine is mother of SEO who have given the birth to SEO but its roots way back during 1958 and 1960’s when Search Engine was born. Apart from that if you want to know the SEO’s history than we can say it might have not exactly born from “Google Page Rank” listing but Google’s birth as search engine ranking could be the most satisfying answer for the birth of SEO, than only it boomed.

2) What do you see more competitive about SEO apart from its competition to remain on top? 


Answer- Apart from remaining on top, the competition is how to strategies and stagnant the position on top and I think ranking on top is easy but positioning on top till end is the more competitive and strategic one.

3) You talk about the strategy, if you are at the position where you are facing the competition to index on top constantly, what will be your strategies?

Now they are checking your core analytical and practical skills of SEO. Here, the answer may vary from person to person and it can be your own strategy which you might have either thought off or used off in the past based on that you can say.

Answer- The strategy could be AdWords or something related to keyword stuffing and parallel concept but practically how we optimize the Search Engine Optimization is the matter of concern here. The organization could have not only Plan A and Plan B but should also be ready with Plan C. Because once the competitors at other end might be knowing what strategy you will use after Plan A basically, they can predict your Plan B. So, does we will do, what we can do here by having Plan C after B is we can force them to launch against our Plan B which they would think would be the final one and strategically we can bounce back with Plan C. So, here they will be trapped and freeze for some time until they come up with new strategy.

That’s done. Your analytical skills have been tested.

  • Description – The meta-description tag is where you would want to put your site’s summary. This is where you put what your site is all about and what you are offering people. It should not be too long because the search engines only read up to a certain number of words. <meta name=”description” content=“Mr.Pandya.com is the financial advisor site by dontgetserious fame blogger Mr. Rohan Pandya ”/>
  • Keywords – The meta-keywords tag is where you put all of the keywords you use in your site. This is basically where you want the words which will take you to the top of the SERPs page to be.

28) What is internal linking?

Answer- It is process of providing hyper-links on website that are connected with same domain.

29) Then what is outbound and inbound linking? (Most Commpn SEO Interview Question)

Answer- Inbound links or commonly known as “backlinks” are the links pointing to your site and search engines like Google, Bing, Yahoo like it when you have thousands of links pointing to your site but sometimes Google penalizes you for it too if you have poor quality and irrelevant backlinks pointing to your site. Yes, because you have no authority over the inbound links which others post for you. Google only likes it when relevant links point to your site but as you have no control over them you cannot control which sites point to your site. But if your content is rich with information and unique then chances are that people will link to your site and there are more chances that those links will be “dofollow” and you will get some free and targeted traffic to your site. Inbound links that are “dofollow” also increase your website’s PR and SERPs and are considered healthy for any blog or website.

And Outbound links are the links pointing to other websites from your website and you have more control over these links. People have different views about outbound links and many say that it is against the SEO rules and search engines can penalize you for doing this. This approach is wrong; I know Google cannot penalize me if I put a link to Google inside my post. My theory is that you should link to relevant content if it gives more information to your readers. Bloggers are of the view that you lose traffic when you put outbound links in your posts but if you share useful resources then chances are that your readers will stick to your blog and will come back in search of more useful resources. But if you do put outbound links in your posts then make sure they are pointing to relevant, original and informative content”.

33) Difference between them?(in response to previous question regarding HTML and XHTML)

Answer- The difference is that HTML is based on SGML and XHTML is based on XML.

34) Can you briefly describe it ( in response to previous answer)

Answer- When using the SGML parser, browsers will continue the parsing even when they encounter a syntax error in the file. This is why so many people think they are doing XHTML when they are sending XML-looking files to the browser. This is actually a mistake since this will trigger many parsing errors in the browser and slow the rendering process. When using the XML parser, browser will stop the parsing when a syntax error is encountered and display an XML error. This is of course only true for browsers that have an XML parser for HTML content, which is not true for Internet Explorer that will only download the file and not display it.
