Top 50 SEO Interview Questions and Answers

On LinkedIn, I regularly get a lot of messages from candidates who are seeking a job or an internship in SEO. But what amazes me is now, people tend to rely on easy shortcuts. I have seen SEO Interview Questions and Answers in the search engine dropdown.

I have spent 10+ years in this field now and have given as well as taken a lot of interviews. The reason why you can use these SEO interview questions and answers, these are from my experience.

While interacting with candidates, I have realized the fact that most of them are not prepared. They just have half-knowledge or very little knowledge.

Another observation is the fact that the candidates are not even able to answer the basic questions related to SEO. Many of them just mug up the definitions of certain terminologies and speak it up in the interview. I hope this article full of SEO interview questions and answers helps them, if not, ”buddy you need to work even more”

.

Being an experienced person in this field, I can understand which candidates have actually worked in SEO or whether the candidate is knowing the basics properly or not.

Practical knowledge is a must in SEO but in order to learn things practically, you must be well-versed with the very basic concepts too.

I thought of writing this article providing SEO interview questions and answers to help candidates prepare for their SEO interviews. SEO is a very vast topic and I cannot cover it entirely.

Also, at different levels, the complexity of the questions will differ. The list of SEO interview questions and answers is never-ending and keeps on updating with time.

But do not worry. I will cover as much as I can. Also, do not just rely on these questions for your interview preparation. But ensure that you know SEO Interview Questions and answers before you appear for your interview. These are the most commonly asked questions.

Most commonly asked SEO Interview Questions and Answers

Before we go ahead with SEO interview questions and answers, do not completely rely on readymade content. Unless you’re very well prepared and thorough with the knowledge.

What is SEO

#3. What are the various SEO related activities?

SEO activities can be of 2 main types – On-Page SEO and Off-Page SEO. 

On-Page SEO, as the name suggests consists of activities on the web page. It involves page structure, navigation, headings, etc.

Off-Page SEO is the SEO that does not require changes on the web page but involves driving traffic to the web page from other sources. It is also known as link building activity.

#4. Do you know coding/programming?

Answer this question as per your skill set.

If you are aware of any coding language, mention it in a proper way like “Yes, I know Java Programming. I studied it during my graduation and also have made an XYZ project in it.”

This question is asked as SEO requires a basic understanding of how websites are made and the terminologies.

Over here, the interviewer wants to understand how comfortable you are while working with scripts. In the above scenario, I mentioned Java, Now, Java has nothing to do with SEO. But yes, if you know any programming language, it will be an added advantage.

If you don’t know any programming language, do not hesitate. Simply say “I do not know any programming language. But if needed, I can learn. I am open to learning new things”.

I would highly recommend you to learn the basics of HTML, CSS and Javascript. PHP would be an added advantage. You don’t have to master these scripts. You just need to get acquainted with them so that in your SEO interview, you can say “I know the basics of HTML, CSS and Javascript. Though I am not an amazing coder, I can understand tags and scripts and even manipulate them if needed”.

#5. What are the various hats in SEO?

Answer such questions precisely

There are three hats in SEO –

  1. White Hat SEO
  2. Black Hat SEO
  3. Grey Hat SEO

Take a pause and let the interview ask you further on this. Do not start explaining things on your own.

The hats indicate the kind of activities performed. There are people who do not follow Google’s guidelines and get involved in unethical ways to drive traffic. Such unethical activities are Black hat SEO tactics. When Google recognizes such activities, the websites involved in such activities are penalized.

White Hat SEO is the SEO that is as per the guidelines of Google. Here, there is no scope of penalty. Google reward such websites by making them rank higher.

Grey Hat SEO is the combination of both white and black hat SEO. Here, there is a chance of a penalty. But, the risk is lesser than that of black hat SEO.

On the other hand, if you consider the search query “buy a black color printed t-shirt for a girl”. Here, any e-commerce player that would have used and optimized for this phrase will rank and there is a high chance of a person buying it.

As it is a more specific search, the user is knowing what he/she wants and does not want to waste time browsing other color t-shirts. Though the search volume for such keyphrases will be less, the conversion rate is going to be much higher for such long-tail keywords.
