Shopping campaigns display Product Listing Ads in their own box on Google Search (separate from text ads), on Google search partner websites that display and link to products for sale, and on Google Shopping (in select countries). Product Listing Ads include rich product information like an image, title, price, and your store or business name. You’ll need to link your Google Merchant Center account to your AdWords account in order to use Shopping campaigns.

Product Listing Ads are a unique ad format that allows you to include an image, title, price, promotional message, and your store or business name, without the need for you to create unique ads for each product you sell. Product Listing Ads show a set of relevant products for a given search. The ads appear in their own box on Google Search (separate from text ads), on Google search partner websites that display and link to products for sale, and on Google Shopping (in select countries).
