Google’s John Mueller said in that video hangout at the 39:51 mark that Google does try to recognize “additional details about information about the author, information about the reviewers, about the website overall, through through a number of ways.” This question was directly related to how Google understands content from medical and health sites.

He said:

This is similar to what we wrote when we covered that Google: YMYL Sites Should Have An Expert To Write The Content and Google Algorithms Detect & Adjust Rankings For YMYL Queries.

The question is how does Google go about doing this? John said “through through a number of ways.” “Partially through the content directly,” he added but also mentioned only structured data is probably not the best way to convey this information to Google in a trusted way.
