One SEO professional asked John Mueller about what kind of structured data they should be adding to their website?
John answered that he would, primarily when it comes to structured data, focus on the things that they have documented in their developer documentation, along with the features that are tied to that.
Instead of saying – “what kind of structured data should I use for this type of website?” John would turn it around to say “what kind of visible attributes do I want to have found in the search results?”
From there, look at what the requirements are for those visual attributes.
Then, can you implement the appropriate structured data to fulfill those requirements.
That’s the direction John would head there.
