A Google Ads metric showing the percentage of times your ads appeared versus how often they could have appeared.
Impression share is the percentage of impressions you received out of the total you were eligible to receive. In paid search, it helps you understand whether you’re missing visibility due to budget, rank, targeting, or bidding constraints.
Impression share is most useful at the campaign level when intent is clear (brand vs generic), because eligibility changes by query and targeting.
