Callout Extension
A callout extension is a short phrase added below a search ad to highlight key features or offers, such as free delivery or 24-hour support, at no extra cost.
A callout extension is a short text phrase added to a Google search ad that highlights a key benefit, feature or offer, appearing below the main ad copy to add more detail about what the advertiser offers.
What Callout Extension Means in Marketing
Search ads have limited space. Headlines and descriptions carry the main message, but callouts handle the supporting detail: the practical reasons to choose this advertiser over the alternatives. Free delivery. No contract. Award-winning customer service. Rated five stars. Open seven days a week.
These are short, specific phrases that communicate value without requiring a click. A user scanning the results page reads the callouts alongside the headline and description, forming a fuller impression of the advertiser before deciding whether to click.
Callout extensions are now officially called callout assets in Google Ads, as part of the broader renaming of extensions to assets. They are part of the ad extensions family.
How Callout Extension Works
Each callout is a text phrase of up to 25 characters. Advertisers can create callouts at the account, campaign or ad group level. Google displays up to four callouts on a given impression, selecting from the available pool based on relevance and expected performance.
Because callouts are short and freeform, they are the quickest asset type to create. The tradeoff is that they require good judgment about what to highlight: vague callouts waste the space.
Callouts work best when they:
- Add information not already in the headlines or descriptions
- Are specific and verifiable, not generic marketing phrases
- Cover a range of different benefit categories
- Are short enough to fit without truncation
Unlike sitelinks, callouts are not clickable. They expand the ad’s content but do not add navigation destinations. This makes them lower-friction to create and approve, since there is no landing page to configure.
Callout Extension Example
A home insurance company creates eight callouts: “No Claims Bonus Protection”, “Settle Claims in 48 Hours”, “Covers Home Office Equipment”, “Multi-policy Discount”, “Cashless Repairs Available”, “Pan-India Network”, “Monthly Premium Option”, “Paperless Claims Process”. On any given impression, Google selects the four callouts most relevant to the user context and displays them below the ad. A user in a home office context sees different callouts highlighted than a user who recently moved.
Why Callout Extension Matters for Marketers
Callouts are the easiest paid search asset to add and one of the most reliable improvements to ad performance. They cost nothing extra, take minutes to create, and consistently increase click-through rates by making ads more informative. There is no good reason not to have them.
Frequently Asked Questions
What makes a good callout extension?
Short, specific phrases that communicate a genuine differentiator or benefit. 'Free Delivery on Orders Over 500' is more useful than 'Great Service'. Callouts should add information not already in the ad headlines or descriptions. Avoid vague marketing language: 'award-winning' without context adds little. Numbers and specifics work well: 'Delivery in 24 Hours', 'Rated 4.8 by 3,000 Customers', 'No Setup Fee'. Keep each callout under 25 characters to ensure it displays in full across devices.
How many callout extensions should I create?
Create at least eight callouts per campaign, since Google shows four at a time on most impressions. Having more gives Google options to choose the most relevant combination for each query context. Use callouts to cover different message categories: delivery and fulfilment, pricing and value, product quality, support and service, security and trust. Spreading callouts across these categories ensures that whatever the user cares about most, there is a relevant callout for Google to select.
What is the difference between callout extensions and structured snippets?
Callouts are freeform short phrases: you write whatever short benefit or feature you want to highlight. Structured snippets are organised by a specific header category chosen from a predefined list, such as Services, Brands or Destinations, and list items under that header. Both expand ad content, but structured snippets present information as a labelled list while callouts appear as individual phrases. Use both: they serve different purposes and appear in different formats.
