Impression share data provides valuable insights into how often your ads show for queries you're participating on. This metric is calculated by taking the percentage of impressions that your ads receive compared to the total number of impressions that your ads could get.
Eligible impressions are estimated using many factors, including targeting settings, approval statuses, and quality. Impression share is a good way to understand whether your ads might reach more people if you increase your bid or budget.
This article shows you how to view impression share data and more information on how impression share works.
How impression and impression share are calculated
Google has updated the calculation for Travel Promotion Ads for Things to do to better align with Search ads and other Google verticals.
- Impression counting: All ads on the carousel receive an impression. This ensures consistency with how carousel impressions are measured across other Google platforms.
- Impression share calculation: To calculate impression share, only your highest-ranked Travel Promotion Ad is assigned an impression and an eligible impression. This aligns with the logic used for Search text ads, so you can compare opportunities across Travel Promotion Ads and text ad formats.
Example
A traveler searches for “beach resorts.” Your account has 4 ads eligible to show in the carousel, and your 2 highest-ranked ads appear.
- Standard impression: 2 (All ads shown are counted)
- Eligible impressions: 1 (Only the highest-ranked is considered)
- Impression share: 100%
The calculation: 1 (highest -ranked ad)/1 (eligible opportunity) = 100%
This allows you to compare reach consistently across Travel Promotion Ads and standard text formats.
