Learn what it is, why it matters, how to measure it, and how to increase your ad visibility. Formula Impression Share (%) · \= · Impressions ReceivedTotal Eligible Impressions · × 100 **Example.** Suppose your ad was eligible to appear 10,000 times based on your targeting, but it actually appeared 7,500 times. In this case, your Impression Share would be 75%. ## Overview ## What it is Impression Share is the percentage of ad impressions you received out of the total you were eligible for. It shows your ad’s visibility in auctions, commonly used in platforms like Google Ads to measure exposure versus competitors. ## Why it matters Impression Share shows how competitive your ads are. A high share means strong reach; a low share suggests missed opportunities from limited budget, low ad rank, or bidding issues. ## How it is calculated Impression Share is calculated by dividing actual impressions by eligible impressions, based on your targeting, bids, quality score, and budget. ## Good and bad values ## A good value A good Impression Share is typically above 70%, indicating strong visibility and competitive presence in the ad auction. However, it may vary depending on industry benchmarks and campaign goals. ## A bad value A low Impression Share (under 50%) may suggest limited budget, low ad relevance, or high competition – resulting in lost visibility and potential conversions. ## Do Use the following strategies to increase your Impression Share and boost ad visibility. 1. 01 ### Increase your daily budget A limited budget can cap your impressions. Raising your daily budget ensures your ads show more frequently throughout the day. 2. 02 ### Improve ad quality score Higher quality scores reduce costs and improve eligibility, increasing your chances of winning more impressions. 3. 03 ### Adjust targeting and bids Refine your targeting and bidding strategy to ensure your ads compete effectively in the auctions where you want visibility. ## Avoid 1. A common mistake is not segmenting Impression Share by campaign or device, hiding performance issues. Ignoring lost share from rank or budget can also lead to wasted spend. ## Related metrics ## Related metrics you might be interested in [Event Count`= Total Number of Specific Events Performed`](/metrics/event-count) [New Sessions`= (New Sessions ÷ Total Sessions) × 100`](/metrics/new-sessions) [Paid Impressions`= Total Number of Times an Ad is Displayed via Paid Media`](/metrics/paid-impressions) [Unique Visitors`= Total Number of Distinct Users Who Visited the Website During a Time Period`](/metrics/unique-visitors) [Unique Users`= Total Number of Individual People Who Interacted with the Website or App During a Time Period`](/metrics/unique-users) ## Related articles ## Articles that use Impression Share [![BigQuery IAM roles: which one to grant, and how to share a dataset](https://cdn.owox.com/www/content-marketing-article/bigquery-iam-roles-and-permissions/thumbnail-20261016124436.png/public) bigquery · BigQuery IAM roles: which one to grant, and how to share a dataset · Oct 16, 2026](/blog/articles/bigquery-iam-roles-and-permissions) ## Customer stories ## Learn how teams ship analytics faster Organizations that scaled analytics without scaling headcount [All case studies →](/blog/success-stories) [Pürblack · "For 10 years I was blind."
