In addition to Google’s general structured data guidelines, review markup should follow these additional guidelines:
Google may display information from aggregate ratings markup in the Google Knowledge Cards. The following guidelines apply to review snippets in knowledge cards for local businesses:
- Ratings must be sourced directly from users.
- Don’t rely on human editors to create, curate or compile ratings information for local businesses. These types of reviews are critic reviews.
- Sites must collect ratings information directly from users and not from other sites.

If you want to use Schema.org markup, the reviews need to be original and generated by your site, not aggregated from a third-party site like Facebook, Yelp, or Google.
