Absolute Top Impression Share measures appearances first among top ads against the estimated opportunities for which the ad was eligible for that placement.
Example of Absolute Top Impression Share
Suppose an ad appears in the first position among top ads 120 times out of an estimated 400 eligible absolute-top opportunities. Its absolute top impression share is 30%; the denominator is eligible opportunities for that placement, not all impressions received.
Why Absolute Top Impression Share matters
It matters because paid search can spend budget quickly. Knowing this term helps teams control intent, targeting, bidding, creative, conversion tracking, and lead quality instead of optimizing for surface-level clicks.

Practical distinction
