Q115. Why is Dwell Time important for SEO?

Ans. This is one of the top SEO questions this year that you should master. Dwell time is how long a user stays on the page of a website after s/he finds it on the Google SERP and goes back to the search results. If the dwell time is less, it means the user did not find the page useful. It is also relative to the SEO content you create.

For instance, a user looking for a quick short answer will not take much time on the page, provided s/he gets the answer without having to leap through distracting video ads that roll automatically as you scroll down content. But if the content is long with an embedded video, the user will obviously spend a considerable amount of satisfactory time and Google will deem it as useful.

Although this is not a direct ranking factor in Google, it is part of the search engine’s machine learning algorithm. It is also different from the bounce rate metric which calculates a single session against all the pages of a website.

Ans. This SEO interview question is again about your familiarity with Google guidelines. You can start by explaining about five factors. 

  • Meaning of your query – Google has language models that can identify the search intent
  • Relevance of webpages – When a page contains the same keyword the user types on the Google SERP and it contains relevant keywords related to the focus keyword 
  • Quality of content – Google gives importance to the reliability of the web page. That’s why simply stuffing relevant keywords does not work.
  • Usability of webpages – This includes page loading speed, the appearance of the webpage on different browsers, etc

  2. Finance
  3. Shopping
  4. Health & safety
  5. Civics, government and law

Q121. Describe Pagination.

Ans. Pagination is a web design tactic of breaking down a huge page into multiple ones. They should be numbered sequentially.

Pagination is important for reducing page load times and improving the user experience, where the user does not have to keep scrolling down. One of the key reasons why it is important from an SEO perspective is that Googlebot cannot effectively crawl and index infinitely. Instead the Google crawler will index a paginated page differently and it can understand a paginated page based on the code, which is a win-win as there is no duplication.

Q122. How do you think ChatGPT will change SEO today?

Ans. Now the benefits of using ChatGPT for an SEO professional lie in automating technical tasks. You can impress your interviewer by mentioning about creating Match Regex in seconds without knowing much of Excel, creating Schema markups without knowing HTML, and even create SEO plugins without coding know-how. There are many other ways of using ChatGPT for SEO that you can read and answer this interview question.
