Win Rate Overview
What Is Win Rate?
Win Rate is a key performance indicator used to evaluate how effectively an ad campaign competes in auctions.
Within AdSpace Adskeeper, it shows the percentage of won auctions in the last 24 hours and how much traffic you're getting based on your bid. This value is always based on the last 24 hours, regardless of the selected date range.
You can view the Win Rate in AdSpace Adskeeper within the Campaigns list. To display it, enable the metric using the column selection filter.

How Win Rate Is Calculated
The win rate is determined using the following formula:
-
Win Rate = (Number of Impressions (Total) / Number of Auctions) x 100 .
For example, if your ad participated in 1,000,000 auctions and won 50,000, this is calculated as:
(50,000 / 1000000) X 100 = 5% Win Rate
Optimization Strategies Based on Win Rate
Below are common scenarios along with recommended actions.
Case 1: Low or Medium Win Rate with Underspending
The Win Rate is Low (less than 40%) or Medium (higher than 40% but less than 80%) and the campaign doesn't spend its budget.
Explanation 1: This means that campaign CPM is too low compared to the competition.
Recommended Actions:
- Increase CPC bids
- Improve ad creatives to boost CTR and competitiveness
Case 2: High Win Rate with Underspending
The Win Rate is High (higher than 80%), and the campaign doesn't spend its budget.
Explanation 2: This means that campaign CPM is high enough compared to the competition, but the amount of available inventory is limited to spending the budget.
Recommended Actions:
- Expand targeting (Geo, OS, browsers, audiences, etc.)
- Review publisher (widget) filters by reducing blacklists or expanding whitelists
- Optimize creatives to achieve higher CTR and capture more clicks from existing inventory
