Understanding Impression Share

What is Impression Share?

IS is the percentage of auctions where your ad actually showed, out of all auctions you were eligible for. 45% IS means your ad was invisible in 55% of eligible searches.

Lost IS to Budget

Your daily budget ran out before the day ended, so Google stopped showing your ads. This is fixable by increasing budget — no quality improvement needed.

Lost IS to Rank

Your Ad Rank was too low — either your bid was too small or your Quality Score was too low. Adding budget won't fix this. Improve QS (ad relevance, landing page, CTR) or increase bids.

Stop checking IS manually

AdPredictor tracks your Impression Share daily and alerts you the moment it drops below your target — before you lose meaningful revenue.
