If you build mobile games in Unity and care about revenue, ad mediation is key. Here’s what it is, how it works, and how to pick the right ad mediation platform for your Unity project.
What Is Ad Mediation?
Ad mediation is the tech layer between your app and dozens of ad mediation networks. Instead of relying on one network to fill your inventory, mobile ad mediation connects you to all of them at once. It automatically sends each ad request to the network willing to pay the most.
Every ad placement in your Unity app mediation setup triggers a real-time auction. The mediation layer polls all connected networks, compares bids, and serves the highest-paying ad. This all happens in milliseconds.
Choosing not to use mediation reduces revenue. No single network consistently fills every impression at optimal rates. Ad mediation solutions maximize both fill rate and eCPM.
How Does Ad Mediation Work?
Know how mediation works so you can optimize your setup. Here’s the real flow:
- A player triggers an ad – maybe an interstitial after a level, a rewarded video for extra coins, or a banner at the bottom.
- The mobile ad mediation SDK sends requests to all connected networks simultaneously, using either a waterfall or a programmatic auction method.
- Networks either bid or pass.
- The network with the highest bid wins, and that ad is displayed.
- Revenue data is recorded, eCPM values are updated, and the system improves for subsequent auctions.
There are two primary mechanisms that ad mediation platforms adopt:
Waterfall Mediation
Traditional waterfall ranks networks by past eCPM. Requests move down the list until someone fills them. This method is slower and less efficient than programmatic bidding.
Programmatic Ad Mediation
Programmatic ad mediation (header bidding, in-app bidding) is now the standard. All networks bid in real time to create a real auction. This usually means 10 to 30 percent higher revenue than waterfall. Every network competes for every impression.
The best ad mediation platforms support both models and often blend them to optimize revenue.
Why Unity Developers Need Ad Mediation
Unity has a strong presence in mobile gaming. Regardless of genre, ad revenue is a critical aspect of your business. Ad mediation for Unity is essential for developers seeking to maximize revenue.
- Maximize Revenue Per Impression – Mediation always selects the highest-paying network for every impression, automatically maximizing your revenue across all regions.
- Eliminate Single-Network Dependency – Rely on a single network, and you’re exposed. If they drop rates or go offline, your revenue drops with them. Mediation distributes risk across dozens of networks.
- Improve Fill Rates – Mediation ensures you capture nearly every available impression, pushing your fill rate close to 100% and eliminating waste.
- Access Premium Demand Sources – Access high-value programmatic exchanges, top brand deals, and exclusive partners that aren’t available without mediation.
- Centralized Reporting and Analytics – Mediation consolidates all key metrics – revenue, eCPM, and fill – into a single dashboard, saving hours previously spent juggling multiple sources.
Key Features to Look for in an Ad Mediation Platform
Not all ad mediation platforms deliver. For Unity, these features actually matter:
In-App Bidding Support: Select top ad mediation platforms with genuine programmatic bidding capabilities. This modern standard outperforms traditional waterfall approaches.
Video Ad Mediation: Video ad mediation drives the most revenue in mobile gaming. Your platform needs strong video support, including VAST/VPAID, all video formats, and access to premium video demand.
AdMob Mediation eCPM Optimization. AdMob mediation eCPM performance is still critical. The best mediation platforms fully integrate with AdMob and use its eCPM data to drive higher yield – whether via Google’s bidding or by ranking AdMob smartly in the waterfall.
Easy Unity SDK Integration. Your ad mediation for Unity SDK should be robust: comprehensive documentation, minimal code requirements, and full compatibility with the latest Unity versions. Ineffective SDKs can cause crashes, lag, and revenue loss.
Network Breadth: A wider ad mediation network increases competition for your inventory. Optimal platforms support 30 to 70 or more networks across all ad formats.
Open Reporting: Transparent reporting at the network level is essential. Access to performance and eCPM data enables effective optimization.
