Somewhere in the last 24 hrs Google changed ( is testing ) the display of Review Summary Snippets in the knowledge panel.
Business Review Summary Snippets in Knowledge Panel |
New Review Summary Display
Current Summary Display
Not Sure What Happened Here.
It looks like the reviews are now segmented into sections based upon terms contained within the review itself: Rooms, Service & facilities etc
These segmented sections then display an aggregated review summary for these determined sections.
The current parsed review snippets remain until there is a large enough data set of reviews to be able to display the new Summary Reviews by sections.
I have not noticed a change to other industries at the moment, it seems like Hotels is the test for this new look.
I have asked for an official statement, insight into the criteria required.
