Google now prompts for user feedback while searching for keywords on Google.com.
As soon as results are displayed for a searched keyword, we noticed this simple question asking for your feedback about current search results.
Question: Did you find what you wanted on this page? (refer image below)
with two simple answers Yes or No.
Once you submit feedback Google thanks and hides the prompt.
NOTE: This prompt doesn’t appear all the time, not sure on what basis Google shows it to users.
This is a very smart move by Google to get real feedback from real users in real time. Checkout and share your thoughts about this feature through Google+ Comments below.
