As in AdWords, Structured Snippets in Bing Ads aren’t clickable. They are designed to showcase particular aspects of the products and services a business offers. For example, “Brands” and “Types” of products available or serviced.
Structured Snippets are available from the Ad Extensions tab at the campaign level. Choose a header (Brands, Types and so on), and then enter a minimum of three snippets. Do not duplicate content already included in an ad. You can associate up to 20 Structured Snippets with a campaign or ad group.
Bing Ads will show as many as 10 snippets with the ads. Structured Snippets from AdWords campaigns will also now import into Bing Ads.
