Reviews can signal both of these attributes by showing that other people enjoy your products or services, and that someone with some authority has approved of these as well.

Seller ratings extensions provide customer-submitted ratings information about sellers next to their Ad Words ads. These reviews primarily reflect customers' buying experience with these businesses, as opposed to particular products. We match these reviews to your ad by pairing the domain of the display URL with the domain on Google Shopping. Seller ratings can appear on desktop and laptop computers and high-end mobile devices with full Internet browsers.

Ways to Improve AdWords Performance

Ad Site links allow you to extend the value of your existing Ad Words ads by providing additional links to specific, relevant content deeper within your site. Rather than sending all users to the same landing page, Ad Site links will display up to four additional destination URLs for users to choose from. On average, advertisers see a 30% increase in click through rate (CTR) for the same ads with Ad Site links.

In fact, ads with longer headlines receive a 6% average increase in CTR compared to the same ads with a standard headline and description. To increase the chances that your ad will appear with the longer headline, make sure that description line 1 is a complete phrase or sentence and ends in punctuation

Location extensions allow you to extend your Ad Words campaigns by dynamically attaching your business address to your ads. In addition to the description lines and URL that appear in your ad text, your ad can also display your business name, address, and phone number. This helps promote your business brand, products, and services and associates your business with a specific location of interest 

Seller rating extensions make it easier for potential customers to identify highly-rated merchants when they're searching on Google.com by attaching your merchant star rating from Google Product Search to your Ad Words ads. These star ratings, aggregated from review sites all around the web, allow people to find merchants that are highly recommended by online shoppers like them. On average, ads with Seller Ratings get a 17% higher CTR than the same ads without ratings.
