# Win Rate Metric
### Introduction
Win rate is an important metric that measures an ad campaign's effectiveness.
It represents the percentage of times the ad was rendered to the user. To simplify, it's the ratio of successful ad auctions to total ad auctions the campaign could participate in.
**Win Rate 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
You can find the win rate metric in MGID Ads in the Campaigns list:

### Optimization Strategies Depending on Win Rate
Let's consider different scenarios and recommended action items per each of them.
- **Case 1:** TheWin Rate is Low (less than 40%) or Medium (higher than 40% but less than 80%) and the campaign doesn't spend its budget.
**Explanation:** This means that campaign CPM is too low compared to the competition.
You can increase CPC bids or try to create more attractive ads that may have higher CTR.
- **Case 2:** TheWin Rate is High (higher than 80%), and the campaign doesn't spend its budget.
**Explanation:** This means that campaign CPM is high enough compared to the competition, but the amount of available inventory is limited to budget spending.
You can add more targeting options (Geo, OS, Browsers, Audiences, etc.) and/or work with publishers (widgets) filtering (reduce blacklist or expand whitelist) to increase available inventory or try to create more attractive ads that may have higher CTR to get more clicks from current available inventory.
