Philipp Lenssen reports that Google introduced a new feedback request for the ads it displays. Can this be considered a new parameter to measure ad and consumer relevance?
A “Was this link useful” option appears when an ad is clicked and the back button pressed. You may choose “Yes” or “No” answers.
In my opinion this new feature will be one more component of the quality scoring of Google ads (Quality Index).
And, don’t forget, this will also be one more cause of click fraud
