Don't Pay Double to Reach the Same People

50.8% of Facebook Audience Network apps also run the AppLovin SDK. That means buying Meta Audience Network inventory costs you twice: once on Meta, once on AppLovin, for the same user in the same app. The result is a noisier lift test and wasted budget.

By the numbers

• 71,510 total Facebook Audience Network apps analyzed
• 36,328 apps also run the AppLovin SDK (50.8% overlap)
• Cross-verified across four independent data sources using zero-trust methodology
• Data current as of April 2026

The problem: cross-network overlap makes measurement less clear

When you run a Meta Audience Network campaign and AppLovin simultaneously, a large share of your impressions go to the same users across both networks. You pay twice, lift test results get diluted, and ROAS suffers. Excluding AppLovin-contaminated apps from your Meta FAN buys is a straightforward fix.

What the free exclusion package includes

• 4 ready-to-upload block lists, pre-formatted and split to comply with Meta's 10,000-entry limit per list
• Step-by-step implementation guide with screenshots for Meta Ads Manager
• App store URLs for all 36,328 identified apps

The methodology

Zero-trust verification across multiple sources. We cross-referenced Meta's Audience Network SDK footprint against AppLovin's footprint using four layers of deterministic matching. No single source trusted. All findings independently corroborated.
