About top and absolute top metrics

We are rolling back the continuous scroll experience globally in all languages across Search. This change will begin in June 2024. Please reach out to your Google representative or Google Ads Help if you have any questions.

Top and absolute top metrics are a set of prominence metrics. Prominence metrics, give you a sense for your ads’ placement on the page.

Search top impression rate “Impr. (Top) %" and Search absolute top impression rate "Impr. (Abs. Top) %" tell you the placement of your ads on the Search engine result pages (SERPs).

Note: Impression share for Hotel campaigns is calculated on where your ad appears in the Hotel ads booking module. Learn more about impression share for Hotel campaigns

Search top impression share (Search top IS) and Search absolute top impression share (Search abs. top IS) help you understand the opportunity for your ads to improve triggering among top ads or in the very first position among top ads.

Unlike average position, these metrics don’t reflect the order of your ads compared to other ads, but the actual placement of your ads on the SERPs.

Note: Search partners don’t distinguish between “top” vs. “others” and won’t be included in location segmentation or impression share data.

Metrics about the location of your ads

You can use these metrics to understand changes in click-through rate (CTR) caused by a change in the location of your ads on the search result page. We don’t recommend you use these metrics as a target to set your bids because, sometimes, they may decrease as bids increase. This happens as higher bids may allow you to enter more competitive auctions in a worse location.
