Unit
- Definition: Callout extensions are short snippets of text that appear below search ads, highlighting specific selling points. They do not require a landing page click but provide additional information that can improve ad relevance.
- Placement: Callouts appear on both desktop and mobile search results, typically as a bulleted list. They are visible on the Google Search Network and can also show on partner sites.
- Cost: Extensions are free to add; you pay only for clicks on the main ad. This makes them a cost-effective way to enhance ad copy without increasing the cost per click.
- Character Limit: Each callout can have up to 25 characters. This brevity forces marketers to condense value propositions into impactful phrases, requiring careful word choice.
- Association Levels: Callout extensions can be set at the account, campaign, or ad group level. Higher-level settings apply to all lower levels unless overridden, allowing flexible management.
- Number of Callouts: You can show up to 10 callouts per ad, but typically 4-6 are displayed. The ad platform selects which ones to show based on relevance and ad rank.
- Impact on CTR: Adding callout extensions can increase click-through rates by 5-15% on average, as they provide users with more reasons to click.
- Ad Rank Factor: Extensions like callouts contribute to ad rank. A quality score component rewards ads with relevant extensions, potentially lowering actual cost per click.
- Cross-Device Behavior: Callouts appear consistently across devices if enabled. However, on smaller screens, the number of visible callouts may be limited, making prioritization important.
- Scheduling: You can schedule callout extensions to show only during specific hours or days. This is useful for promoting time sensitive offers like flash sales or weekend discounts, ensuring the callout aligns with business operations.
- Best Practices: Use action oriented language, focus on unique value, and test different callout sets. Regularly rotate underperforming callouts and avoid repetition with other extensions or ad copy to maximize relevance and effectiveness.
- Performance Tracking: In Google Ads, callout extensions have separate reporting columns showing impressions, clicks, and conversions attributed to them. This data helps advertisers measure direct impact and refine callout strategies over time.
