The extension is rolling out globally.
Bing Ads has released Structured Snippets for text ads and is rolling them out globally over the next few weeks.
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 and ad group levels. 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.
