What is Google AAP and Google MMP for Mobile Apps?

What is Google Mobile Measurement Partners (MMP)?

An MMP is a third-party service that helps mobile app developers and marketers track the performance of their advertising campaigns across various platforms.

Popular MMPs include:

  • AppsFlyer
  • Adjust
  • Branch
  • Singular
  • Kochava

The MMP attribute installs, in-app events, and user behavior to specific ad campaigns, helping marketers understand which channels are driving value.

What is Google Mobile App Attribution Partner (AAP)?

Google's App Attribution Partner (AAP) is a program that allows MMPs to integrate directly with Google Ads in a privacy-conscious and secure way.

Google restricts how much raw user-level data is shared, complying with privacy regulations like GDPR and CCPA.

Only a few certified MMPs are part of the AAP. This ensures integrations with Google Ads are officially supported, accurate, and stable.

Google certified App Attribution Partner:

  • Adjust
  • Airbridge
  • AppsFlyer
  • Branch
  • Kochava
  • Singular
  • Tenjin

How Google AAP/MMP Works with a CMP

Third-party AAPs (App Attribution Partners) rely on user consent signals to accurately pass app conversion data and consent status to Google Ads for proper attribution and campaign optimization. These consent signals are collected through a Consent Management Platform (CMP), such as UniConsent Mobile SDK.

To remain compliant and ensure accurate attribution:

  • For users in the European Economic Area (EEA), you must capture and store consent status before sending any app conversion data to your AAP.
  • If a conversion is sent without valid user-level consent, Google Ads may fall back to using gbraid for non-user-level app conversion measurement, which limits attribution precision.

Always integrate a CMP in your app to gather consent signals before initiating conversion tracking, especially for regions governed by strict privacy regulations like the GDPR.

Why Google AAP/MMP Is Important for Developers and App Marketers

Mobile Measurement Partners (MMPs) enable app developers and marketers to track where users originate: whether from Google Ads, Meta, TikTok, or other channels. Through Google’s App Attribution Program (AAP), MMPs can continue to attribute installs and in-app actions from Google Ads accurately, even under Google's stringent privacy policies. This ensures you clearly see which campaigns are truly driving results.

Effective attribution helps you identify top-performing ad creatives, targeting strategies, and channels. Without it, you risk wasting budget on campaigns that don't convert. With reliable insights, you can maximize return on ad spend (ROAS) and make smarter decisions about where to invest.

Google AAP also enforces strict privacy standards, ensuring all data shared with MMPs remains compliant with: GDPR (General Data Protection Regulation – EU), CCPA (California Consumer Privacy Act – US) and Android Privacy Sandbox.
