# Banners—Slot Reserve Prices for Manual Bidding

> Set minimum CPM and CPC reserve prices per banner slot to ensure optimal revenue thresholds

August 4, 2025Ad PlatformImprovement

We've added **slot-level reserve prices** for banner campaigns, allowing marketplaces to set minimum **CPM** and **CPC** thresholds for individual banner slots. This granular control ensures optimal monetization while maintaining campaign performance standards.

## Key Benefits

**Granular Revenue Control**:
Set specific minimum bid thresholds for each banner slot based on placement value and performance

**Intelligent Fallback Logic**:
Slots without specific reserve prices automatically inherit marketplace-level reserve settings

**Campaign Validation**:
Manual bidding campaigns receive clear warnings when bids fall below slot reserve thresholds

**Centralized Management**:
All slot reserve prices are stored and managed through central services for consistency

## How It Works

### Reserve Price Hierarchy

When evaluating banner campaigns, the system follows this priority order:

1. **Slot Reserve Price** - If set, this takes precedence
2. **Marketplace Reserve Price** - Used as fallback when no slot-specific price exists

### Campaign Impact

* **Manual Bidding Campaigns**: Must meet or exceed slot reserve prices to participate in auctions
* **Autobidding Campaigns**: Bid amounts automatically adjust to meet minimum slot requirements
* **Exclusive Campaigns**: Unaffected by reserve price restrictions

## Setting Slot Reserve Prices

To set or update reserve prices for your banner slots, please follow these steps:

1. **Prepare a CSV File**: Create a configuration file listing the `slot_id` and your desired minimum `cpm_reserve_price` and `cpc_reserve_price` reserve prices for each banner slot.

2. **Contact Your Representative**: Share the CSV file with your Topsort account manager. Our team will handle the configuration and apply the new thresholds.

3. **Monitor Performance**: After the changes are live, monitor your campaign participation and slot revenue to ensure the new reserve prices are meeting your goals.

## Validation and Warnings

When creating or editing manual bidding campaigns, the system will:

* Check bid amounts against relevant slot reserve prices
* Display warnings like "Maximum \[CPM/CPC] must be at least \$\[slot reserve price]" when thresholds aren't met
* Prevent campaign participation if bids remain below minimum requirements
