Google "Custom Search Ads" latest in AdSense for search product are "designed to fit your existing search results' look and feel. Instead of pre-defined sizes, you can specify the precise width of each ad unit along with the number of individual ads to display, the ad layout, font size, font face, and much more," revealed Google.
"With Custom Search Ads, we can rapidly develop and launch new search ad formats and extensions without requiring you to update your search code. For e.g., on Google's results pages we've been busy testing new search ad extensions to provide users with info like locations, product images, page links, and merchant information. Two of these new formats are available today in Custom Search Ads: Ad Sitelinks and Seller Ratings."

And, "Seller ratings add star ratings below a merchant's ad aggregated from review sites across the web. These help highlight ads for merchants highly recommended by online shoppers," explains Google
