Callout extension - Callout extensions let you include additional text so you can show more detailed information about your business, products, and services. This article explains how to create, edit, remove, and schedule callout extensions. - Campaign types: Callout extensions can be added to Search Network campaigns and Search Network campaigns that have opted into the Display Network. - Shorter text means more callouts can show in your ads. Think of a callout as a bullet point, rather than a complete sentence like "Free shipping" instead of "We have free shipping." - Character limits: Callout text is limited to 25 characters in most languages, or 12 characters in double-width languages (like Chinese, Japanese, and Korean).
