Google Shopping Ads are visual ads that display your products with image, price, store name, and reviews directly in Google search results. They run on the product feed from Google Merchant Center. They deliver higher CTRs than text ads and attract high-intent buyers.
When someone searches 'Nike Air Max sneakers', they see 8-12 products at the top of the Google page with photo, price, and store. Your ad appears if you have the product in your feed with a competitive price and an optimized feed.
