During a Question and Answer segment in a hangout, one SEO professional asked John Mueller about incorrect structured data.
They are seeing competitors showing up in the search results with aggregate rating, along with high-price, low-price rich results. And this is used on e-commerce product category pages.
Based on Google documentation,it looks like this is not an improved use case.
They wanted to check and verify that – if they are understanding the documentation correctly – that this is something that they should be working on also.
John explained that yeah, unfortunately, not everyone implements things the way that they have in Google documentation.
Whether this is on purpose, that they are doing things in ways that don’t follow the documentation guidelines, or by mistake, it’s hard to tell.
However, John urges that you should always do your best to follow Google’s documentation guidelines when trying to implement these features, such as structured data for category pages.
This happens at approximately the 33:15 mark in the video.
