How have you utilized structured data?
The interviewer wants to know if you have experience using structured data to boost your SEO. They ask this question to determine your experience level and if you'll need training in this area if hired.
If you don't have experience using structured data, tell the interviewer but confirm you're willing to learn. You should be familiar with what structured data is before going into the interview, even if you haven't used it. If you have experience using structured data, explain how you've used it in the past.
"I do have experience using structured data to improve SEO results. I've used Google's Structured Data Markup Helper for product and FAQ markup and seen good results."
