Choosing the right ad mediation platform in 2026 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 such as interstitials and rewarded videos
  • Enables Ad ROAS campaigns, helping scale user acquisition through AppLovin

Cons

  • No COPPA support, making it unsuitable for child-directed apps

2. Google AdMob

Pros

  • Excellent performance with banner ads
  • Google’s demand source delivers strong ad quality and large impression volumes
  • Stable and reliable fill rates, especially in Tier-2 and Tier-3 regions

Cons

  • Product innovation has slowed, and the platform has changed little in recent years

3. Unity LevelPlay

Pros

  • Advanced segmentation capabilities for optimizing by geography, device, or user behavior
  • Recent upgrades such as Vector and multi-ad-unit support
  • A great option for teams already building their apps or games with Unity

Cons

  • ARPDAU performance can be inconsistent depending on the market and game genre

So Which One Should You Use?

The reality is that there is no one-size-fits-all answer.

Performance can vary significantly depending on factors such as:

  • Country
  • User segment
  • Ad format
  • Game or app category
  • Time of year

This is why many publishers experiment with different setups before committing to a single mediation platform.

How Loomit Helps You Decide Smarter

Loomit was built to help publishers take full control of their ad monetization strategy — from testing and comparing mediation platforms to dynamically optimizing performance across formats, regions, and networks.

With Loomit, you can:

  • Run A/B/C tests between MAX, AdMob, LevelPlay, or other mediators
  • Split traffic across mediators however you want
  • Mix mediators by format (for example: AdMob for banners, MAX for full-screen ads)
  • Target specific regions or user segments
  • Keep control groups live to measure real performance changes
  • React quickly to shifts in monetization performance without complex migrations

Instead of relying on guesswork or large infrastructure changes, Loomit allows teams to continuously experiment and optimize their monetization stack.
