Ads.txt & app-ads.txt generator
Publishers with both a website and apps usually keep two files in sync by hand. Keep one list of networks instead and generate both files from it.
Open the free app-ads.txt generator
One network list, two files
Set up your ad networks once — Google AdMob or Ad Manager, AppLovin, Unity, Mintegral, Meta and others. The generator renders the lines of every network; save the result as ads.txt for your site and as app-ads.txt for your apps.
When the two files differ
- Web-only demand partners (header bidding, display SSPs) belong only in ads.txt.
- Mobile ad networks and their app-specific resellers belong only in app-ads.txt.
- Google uses the same pub- ID format for AdSense, AdMob and Ad Manager — but your web and app accounts can have different IDs. Copy each from its own dashboard.
Keep them current
Networks add and remove resellers regularly. A hosted app-ads.txt on App TXT is re-rendered whenever a template changes, so your apps’ file never goes stale.
FAQ
Do I need both ads.txt and app-ads.txt?
Only if you monetize both a website and apps. Websites need ads.txt, apps need app-ads.txt on the developer website.
