Top 3 Ad Mediation Platforms in 2025

And How Loomit Helps You Choose the Best One

Choosing the right ad mediation platform in 2025 can make or break your monetization strategy. Based on what we’ve seen across dozens of mobile publishers, the three most common options are:

• AppLovin MAX
  
• Google AdMob
  
• Unity LevelPlay
  

Each one has its strengths — and its limitations. Let’s break them down:

1. AppLovin MAX

Pros:

• Strong CPM performance, especially in Tier-1 markets like the US
  
• Excellent results in full-screen formats: Interstitials and Rewarded Videos
  
• Allows Ad ROAS campaigns, helping scale UA through AppLovin
  

Cons:

• No COPPA support – not suitable for child-directed apps
  

2. Google AdMob

Pros:

• Excellent performance with banner ads.
  
• Google’s demand source commands the largest share of impressions and consistently delivers above-average ad quality.
  
• Stable and reliable fill rates, especially in Tier-2/3 regions
  

Cons:

• Product innovation has slowed – the platform looks and works much like it did years ago
  

3. Unity LevelPlay

Pros:

• Advanced segmentation options for optimizing by geography, device, or user behavior
  
• Recent upgrades like Vector and multi-ad-unit support
  
• Great fit for teams already using Unity for development
  

Cons:

• Inconsistent ARPDAU depending on market and game type
  

So Which One Should You Use?

The truth is: there’s no one-size-fits-all answer. Performance can vary widely based on:

• Country
  
• User segment
  
• Ad format
  
• Game/App type
  
• Time of year
  

That’s where Loomit comes in.

How Loomit Helps You Decide Smarter

Loomit was built for exactly this challenge: helping publishers take full control of their ad monetization strategy — from testing and comparing mediation platforms to dynamically optimizing performance across formats, regions, and networks — all without the usual technical overhead.

With Loomit, you can:

• Run A/B/C tests between MAX, AdMob, LevelPlay (or others), splitting traffic however you want
  
• Mix mediators by format (e.g., AdMob for banners, MAX for full-screen)
  
• Target by region or user segment (e.g., Unity LevelPlay for LATAM, MAX for US)
  
• Keep control groups live to measure real-time performance changes
  
• React to shifts in monetization automatically — no more guesswork or hard migrations
  

We’ve seen this across 30+ publishers:
In many cases, one mediation platform outperforms in the US, another delivers stronger results in India, and a third consistently wins on banners worldwide. Without proper testing, you’d never know — and you could be leaving money on the table.

Real Results

“Switching mediators used to take us weeks. With Loomit, we were able to run a clean test in 48 hours — and we discovered a 17% boost in ARPDAU just by changing formats in one country.”
