Effective August 1, Google will remove the “Rich Results” filter from the “View in Search” section of its Search Console performance reports.

Google Search Console currently supports 19 types of search appearance in performance reports to help site owners understand how their sites perform in Google search. If a site is receiving multiple types of rich results, then combining all the data in one view is no longer useful to the site owner.

The Rich results filter included data for all the rich results at once. This is no longer required as Google now has filters for a wide variety of result types such as Event, FAQ, HowTo, etc.

Google noted that disabling the filter will not affect site traffic in any way, this is just a change in reporting.
