Google has updated its FAQ structured data guidelines in which you can longer markup the same question and answer if it appears on multiple pages on your site. That means site owners can mark up only one instance of their FAQ content that appears on multiple pages.
The following line has been added to Google’s developer documentation for FAQ structured data:
“If you have FAQ content that is repetitive on your site (meaning, the same question and answer appear on multiple pages on your site), mark up only one instance of that FAQ for your entire site.”
FAQ Page schema is a type of structured data that enhances a search result by adding a drop-down feature below the search result. This drop-down contains three or more questions that help strengthen your result by answering the full intent of the search. It also enables users to push their competitor’s listings to the next page easily. So there is no point in wondering why publishers are trying to make use of the system.
To address this issue, the company is updating its guidelines for the use of FAQ structured data. Although you can still add the same question on multiple pages, you should desist from marking it up every time.
If you seem to violate Google’s structured data guidelines repeatedly, your website will end up losing its eligibility to appear in featured snippets.
