Endorsal now supports Google's aggregate rating review snippets, using JSON schema injection.
Head to app.endorsal.io/property/schema to set it up.
Available schema types:
— Local Business
— Software Application
Please note: due to recent changes in Google's policies, we cannot guarantee that star ratings will be displayed for the "Local Business" or "Organization" schema types. Read more about it here: webmasters.googleblog.com/2019/09/making-review-rich-results-more-helpful.html
