Have you typed a Google search and noticed a popover window from google at the bottom?
Satisfied with these results?
Looks like you can rate from very dissatisfied to very satisfied.
In this example, we rated very satisfied then received the below prompt – Thanks for your feedback!
It's interesting to note there was no form to provide written feedback, which makes us believe the rating is based on the layout of search results and not as much as the material results. In any case, it’s cool to be able to respond to Google like this!
