Publisher Monetization

Win Rate — Definition & Explanation

The percentage of submitted bids that win the auction. Used to evaluate demand partner competitiveness. Low win rates suggest bids aren't competitive; very high win rates may suggest the demand source has unique, uncontested demand.

How Win Rate Works

Win rate = auctions won / bids submitted × 100. In header bidding, win rates are tracked per demand partner. Low win rates indicate the partner's bids are consistently outbid by higher-paying demand sources.

Why Win Rate Matters for Publishers

Win rate analysis helps optimize header bidding configurations by identifying demand partners who add competition without adding win probability, indicating they may not be worth the latency cost.

Frequently Asked Questions

What is a typical header bidding win rate?

Win rates of 5-25% per partner are common in competitive header bidding environments. Very high win rates (50%+) may indicate insufficient competition from other partners.

Should publishers prioritize partners with high win rates?

High win rates at competitive CPMs are ideal. High win rates at low CPMs may indicate a partner winning by default rather than through competitive bidding.
