What prevents json-LD from setting an overestimated rating with aggregateRating? Why is it needed at all, rating? If nothing prevents it from doing so after some time everyone will set their own maximum rating.
1 answer
The point is that it is not always convenient to output everything microdata due to the html features.
Therefore, as an alternative, an option with json-LD is given that can be generated from aggregated data.
If this is a page with a review of the film / restaurant / book / car / gadget / ... there is a rating not on the page / site itself, but according to the author of the review
+ In case of manual manipulations with a rating, there can be such an outcome:
Robots can automatically turn off the display and taking into account micromarking for this site
In the event of a complaint to the support service, manual sanctions may be imposed on the search engine with a decrease in the place in the search results.

- So what prevents me from manually setting any overrated rating? And what prevents it from doing to others? - Yuri Svetlov
- Nothing. In this case, Google and other poskovikov have a great phrase - they do not guarantee anything as will be indexed / displayed in the issue. The robot will suspect a cheating / illogical situation - will send it to the forest and, if anything, will take it from other sources - facebook, foursquare, google maps and other popular ones - Makar
- oneAdd your answer like this: There is a possibility that Google’s robots will find an overestimated rating false and it will no longer appear on the snippets of this site in search results, or it will apply more stringent measures against the violating site. - Yuri Svetlov
- oneAs it is -According to the Google documentation, you can use markup with structured data for review and evaluation: local business, movies and books. The ability to identify reviewers is required, for example, with social links. networks (Google+) or website. Otherwise, there is a risk of receiving penalties for spam in the markup with structured data. - Yuri Svetlov
