The benefit of a paid search ad with seller ratings is that they let the searcher know that the advertiser is rated well by their customers. An ad with seller ratings helps customers make more informed decisions when clicking on an ad and purchasing from a company.
A user is more likely to click on an ad with seller reviews versus an ad without reviews. Ads with seller ratings generally earn more clicks than an ad without, thus increasing your click-through-rates.
Ads with seller ratings can be seen on Google.com and Google Search Partners on both desktop browsers and high-end mobile devices that have full Internet browsers.

Ads must meet the following criteria to be eligible to appear with seller ratings extensions:
Please note that you do not need to have a Google Merchant Center account for your ads to be eligible for seller ratings. In addition, if you have a seller rating of four stars or higher but have bad customer reviews, users will be able to read any bad reviews.
