Callout extensions are similar to sitelinks, but without the links. Google recommends that advertisers use callout extensions to draw attention to unique selling points and important product details and benefits. You can feature up to four callouts in your ad, each limited to 25 characters each, and must have at least two callouts for them to display.
Callout extensions can be used with other ad formats, like sitelinks, and are created, scheduled and managed within the Ad Extensions tab. You can add callouts at the account, campaign or ad group level, allowing you to use general information at the account or campaign level and specific callouts for each ad group.
