❓ What is it
The Extension Audit provides a detailed overview of how ad extensions are being used across your top-performing ad groups. It helps you identify gaps and optimization opportunities for ad extensions at the ad group, campaign, and account levels.
The audit is available in both charts and tables, and is updated automatically.
▶️ Why is it important
Ad extensions improve ad visibility, click-through rate, and relevance — but only if they’re implemented properly.
This audit helps you:
Prioritize high-spend ad groups that are missing key extensions.
Spot missing or under-leveraged extensions that can hurt performance.
Increase relevance by identifying cases where extensions are only added at the campaign or account level and not tailored to the specific ad group.
Quickly filter and take action across all your ad groups.
🔍 How does it work?
The extension audit is divided into four key sections per ad group:
Spend (Last 30 Days)
Shows how much each ad group has spent in the past 30 days.
Helps you focus on the most important ad groups first.
Missing Extensions
Identifies extensions that are not active at any level (ad group, campaign, or account).
In the UI, hovering over the chart shows which ones are missing.
Campaign-Level Extensions
Extensions that are active and eligible for the ad group only at the campaign level.
Suggests an opportunity to make them more specific and relevant by adding them directly to the ad group.
Account-Level Extensions
Extensions that are active and eligible for the ad group only at the account level.
Opportunity to add them directly at the ad group level for more relevance.
