  Reserve prices (also called bid floors) set the minimum acceptable prices for
  your ad inventory, ensuring premium placements don't sell below their value.
</div>

## Why Reserve Prices Are Important

<Tip>
  **Protect Your Inventory**: Prevent premium ad slots from being undersold in
  low-competition auctions while encouraging higher bids from autobidding
  campaigns.
</Tip>

* **Revenue Protection**: Maintain minimum yield from valuable ad placements
* **Market Efficiency**: Encourage competitive bidding
* **Inventory Optimization**: Differentiate pricing between premium and standard slots

## Types of Reserve Prices

### Sponsored Listings

**By Product Category:**

* e.g., **Electronics:** min $5 CPM, $0.50 CPC
* e.g., **Fashion:** min $3 CPM, $0.30 CPC

**By Geolocation:**

* e.g., **New York:** min $8 CPM, $0.65 CPC
* e.g., **California:** min $7 CPM, $0.60 CPC
* e.g., **Texas:** min $4 CPM, $0.35 CPC

### Banner Ads

Set minimum CPM and CPC per **specific slot**:

* e.g., **Homepage hero banner:** min $15 CPM, $1.00 CPC
* e.g., **Category page sidebar:** min $8 CPM, $0.60 CPC
