Publisher Monetization

Floor Price — Definition & Explanation

The minimum CPM a publisher is willing to accept for their ad inventory. Bids below the floor price are rejected. Floors can be set globally, by placement, by geography, or dynamically adjusted based on real-time signals.

How Floor Price Works

Floor prices are configured in the SSP and applied to every bid request. When buyers submit bids, only those meeting or exceeding the floor are eligible to win. Optimal floor strategy balances maximum CPM capture with fill rate maintenance.

Why Floor Price Matters for Publishers

Floor prices are the single most direct lever publishers have over their CPMs. Poorly set floors (too high or too low) are the most common cause of revenue underperformance.

Frequently Asked Questions

How do I set the right floor price?

Start with data — analyze your historical bid landscape by segment and set floors just below the density of bids. Dynamic floor pricing automates and continuously optimizes this.

Should different placements have different floors?

Absolutely. Above-the-fold, viewable placements should have higher floors than below-fold units. Video floors should be significantly higher than display.
