Google’s John Mueller has revealed that the search engine might help extra structured knowledge sorts relying on what number of web sites are utilizing it.

When Google thinks about what kind of structured knowledge to help subsequent, it seems to be to see what number of websites are literally utilizing it.

If an unsupported structured knowledge kind is extensively applied then Google might resolve to help it in search outcomes.

Conversely, if Google sees nobody is utilizing a selected kind of structured knowledge, then it’s going to seemingly not be thought-about any additional.

This subject got here up in a current Google Webmaster Central hangout the place the next query was requested:

“Is the merchandise kind ‘service’ supported by Google for opinions and scores? The overview pointers point out providers, however the supported merchandise sorts doesn’t embrace providers.”

In response, Mueller confirmed that Google’s developer website is the authority on supported merchandise sorts.

The developer website is constantly up to date, so if it says a structured knowledge ingredient is supported or not supported then that info is correct.

With that mentioned, website homeowners shouldn’t keep away from utilizing explicit sorts of structured knowledge simply because they’re not formally supported.

If Google sees that websites are adopting an unsupported structured knowledge kind then that will affect Google’s choice to help it sooner or later.

You’ll be able to hear the total query and reply within the video beneath (beginning at 45:30):

“I notice we help rather a lot of differing types of structured knowledge, and typically it’s difficult to determine which sorts apply to your explicit case. However, basically, we attempt to be as express as potential in these pointers as regards to what we help.

That doesn’t imply you shouldn’t use something that we don’t help. It’s at all times a bit of a hen and egg downside in that if we take into consideration the subsequent kind of structured knowledge that we do need to help, and we see no one’s truly utilizing it like that on-line, then maybe we’ll attempt to discover one thing else.

So if you are feeling like you really want to make use of this explicit kind of structured knowledge in your particular use case, then by all means use that even if we don’t truly use it instantly as a visual ingredient within the search outcomes.”
