When to use price floors in Google Ad Manager?
Price floors in Google Ad Manager let publishers set the minimum CPM (cost-per-thousand impressions) they are willing to accept for their ad inventory. Used strategically, price floors can increase revenue by filtering out low-paying bids and encouraging higher competition among advertisers. However, if set incorrectly, they can lead to reduced fill rates and lost revenue opportunities.
In this blog, we will explore when to use price floors in Google Ad Manager and how to apply them effectively to protect and enhance your earnings.
What Are Price Floors and How Do They Work?
An introduction to price floors and their function in programmatic ad auctions.
In digital advertising, especially within Google Ad Manager, price floors act as the minimum price at which an ad impression can be sold. These thresholds ensure that your inventory is not undervalued in real-time bidding (RTB) environments.
Price floors come into play in programmatic auctions, where multiple buyers bid on available impressions. By setting a floor, publishers can control their revenue potential by rejecting bids below a certain value. There are two types:
• Hard Price Floor: Bids below this amount are rejected outright.
• Soft Price Floor: Bids below this may still be accepted, but the system may prioritize higher bids with dynamic pricing logic.
By strategically implementing price floors, publishers can optimize yield, maintain brand value, and reduce low-value ad clutter.
When Should You Apply Price Floors?
Scenarios where price floors are effective—such as premium content, high-traffic periods, or exclusive inventory.
Setting price floors is not a one-size-fits-all strategy—it is most effective when applied under specific conditions that justify a higher value for your ad inventory. Here are some ideal scenarios:
• Premium Content: If your website hosts high-quality, niche, or exclusive content (e.g., finance, tech reviews, medical blogs), advertisers are often willing to pay more to reach your audience.
• High-Traffic Periods: During peak seasons like festivals, shopping events (e.g., Black Friday), or viral news coverage, increased advertiser demand means you can raise the floor to get better CPMs.
• Exclusive or First-Party Data Inventory: If you are offering ad spots with detailed audience targeting (age, location, interests), this added value can support higher price floors.
• Brand-Sensitive Pages: Pages that must maintain premium ad quality (like corporate blogs or partner pages) benefit from filtering out low-paying or irrelevant ads.
Applying price floors smartly ensures your inventory is monetized at its true worth—maximizing revenue without compromising ad quality.
How to Set and Adjust Price Floors in GAM
Step-by-step guidance on creating unified pricing rules and experimenting with CPM thresholds.
Setting up price floors in Google Ad Manager (GAM) involves using Unified Pricing Rules to define the minimum CPM (cost-per-thousand impressions) you will accept from programmatic buyers. Here is how you can do it:
1. Access Unified Pricing Rules
• Go to your Google Ad Manager account.
• Navigate to Inventory > Pricing rules > Unified pricing rules.
2. Create a New Rule
• Click “New Unified Pricing Rule.”
• Name the rule descriptively (e.g., “Homepage Desktop Floor”).
3. Set Target Inventory
• Choose the inventory this rule applies to—specific ad units, placements, or key-values.
• Select device types, geographies, or ad sizes if needed.
4. Define the Price Floor
• Under the CPM value, enter the floor price you want.
• You can set multiple CPMs for different buyer types if applicable.
5. Apply and Monitor
• Save and activate the rule.
• Monitor performance in Reports > Programmatic Revenue to see how it is affecting your fill rate and CPM.
6. Test and Optimize
• Start with moderate floors and test different CPM thresholds.
• Watch for drops in fill rate or impressions—too high a floor can reduce ad delivery.
Using Unified Pricing Rules lets you balance maximum revenue potential with ad delivery consistency, making sure your inventory sells at fair market value without being undervalued.
Risks and Best Practices in Using Price Floors
Tips for avoiding overpricing, maintaining fill rates, and using data to inform floor strategies.
While price floors can boost revenue, setting them without a strategic approach may backfire. Here is a breakdown of the risks involved and best practices to follow:
⚠️ Common Risks
• Overpricing Inventory: Setting floors too high can price out potential buyers, resulting in unsold impressions and lower fill rates.
• Reduced Demand: Advertisers may choose to shift budgets to cheaper inventory if yours is perceived as too expensive.
• Decreased User Experience: If ad fill drops, users may see fewer or repetitive ads, affecting overall engagement.
✅ Best Practices
• Start Conservative: Begin with moderate CPMs and gradually raise floors based on performance data.
• Use Historical Data: Analyze past auction insights, bid ranges, and CPMs before setting any floor price.
• Segment by Value: Apply different floors based on ad unit quality, device type, or geography (e.g., higher floors for desktop homepage vs. mobile footer).
• Monitor Regularly: Keep an eye on fill rates, CPMs, and total revenue—adjust quickly if you see negative trends.
• A/B Test Floor Levels: Run experiments to compare performance with and without specific price floor rules.
By applying these data-driven strategies, you can strike the right balance between maximizing revenue and maintaining healthy demand and ad delivery across your inventory.
