Callouts can improve your text ads by promoting unique offers to shoppers, like free shipping or 24-hour customer service. When customers see your ads, they get detailed information about your business, products, and services.

How they show

2 to 6 callouts show in addition to the text of your ad. Ads with callout extensions can show at the top and bottom of Google search results. When callout extensions show, they appear below your ad copy.
