In-depth SEO interview questions
Question 1
How do you handle a website that has been penalized by Google?
Answer 1
If a website is penalized by Google, the first step is to identify the type of penalty—manual or algorithmic. Next, I would conduct a thorough audit to find the root cause, such as unnatural backlinks or thin content, and take corrective actions like disavowing bad links or improving content quality. After making the necessary changes, I would submit a reconsideration request if it’s a manual penalty and monitor the site for recovery.
Question 2

Structured data, often implemented using schema.org markup, helps search engines better understand the content of a webpage. It can enhance search listings with rich snippets, such as ratings, reviews, and event details, which can improve click-through rates. Proper use of structured data can also increase the chances of appearing in featured snippets and other SERP features.
