What is Impression share?
Impression share is the percentage of total available impressions that your ads actually receive in a given market or auction. It is calculated by dividing the number of impressions your ad received by the estimated number of impressions it was eligible to receive, based on targeting, budget, and quality factors. Monitoring impression share helps advertisers understand whether they are losing visibility due to budget constraints or low ad rank, and it directly informs bidding strategy and creative optimization decisions.
How it relates to AI UGC
Higher ad relevance scores lead to better auction outcomes and increased impression share. By using AI UGC tools like ppl.studio to produce a wider variety of creative—featuring diverse personas, settings, and messaging angles—brands can improve relevance scores across audience segments and win more impressions without raising bids.
