Make my app-ads.txt
app-ads.txt is a small text file on your website that tells advertisers "these companies may sell ads in my app". Without it many advertisers pay less, or nothing. This page builds the file for you. Nothing you type leaves your browser.
- Your AdMob Publisher ID (AdMob → Settings → Account information). It looks like
pub-1234567890123456. - Tick the networks you connected and paste the lines each one gives you (where to find them is under each box).
InMobi dashboard > Inventory > app-ads.txt gives a personalized snippet with your InMobi payment/seller ID; verification status under My Account > Manage App-ads.txt. Format: 'inmobi.com, <your seller account ID>, DIRECT, 83e75a7ae333ca9d' (83e75a7ae333ca9d is InMobi's TAG ID for all lines; do NOT use the publisher GUID).
Unity dashboard > Organization settings > App-ads.txt: the App-Ads URL field shows the full list of authorized sellers in the right format; copy the whole list into your app-ads.txt (Unity says to re-check it monthly). Unity says banner demand drops sharply without app-ads.txt. The exact unity.com line is generated per organization (not verified here as a fixed string).
Copy your line from Monetization Manager (the app-ads.txt section of your property/account settings). Fixed format: 'facebook.com, <your Meta publisher/business ID>, DIRECT, c3e20eee3f780d68'. The ID in the second field is per account.
AppLovin dashboard > Account > General > App-ads.txt Info lists your lines; also register your developer website root domain under Account > General > Basic Info. Format: 'applovin.com, <your ID from that page>, DIRECT' (copy the exact string; AppLovin shows no fixed certification ID in its example).
Mintegral publishes its app-ads.txt guidance (linked from Google's guide); your lines come from the Mintegral developer dashboard. The exact fixed line format was not confirmed from an official source here; copy it from the dashboard.
Download the current list from https://publisher.vungle.com/vungleAdsTxt and append it. Format: 'vungle.com, <your Publisher Account ID / Seller ID (top-right of the dashboard)>, DIRECT, c107d686becd2d77'. Also set your developer website root domain in the Liftoff dashboard.
Copy the ironSource authorized resellers block from https://developers.is.com/ironsource-mobile/general/app-ads-txt/#step-5 (now also on docs.unity.com), replacing OWNERDOMAIN and putting your Publisher ID (ironSource platform > Account > API tab > Publisher ID) in the direct line. Exact fixed line not confirmed here.
Follow DT's app-ads.txt article (https://developer.digitalturbine.com/hc/en-us/articles/360009975198-app-ads-txt); lines use your DT Publisher ID (DT Console > User Profile). The exact fixed line was not confirmed from an official source here; copy from DT's article.
Chartboost dashboard > Monetization > Tools > App-ads.txt (scan + verifier); follow https://docs.chartboost.com/en/monetization/publishing/app-ads-txt/. Fixed line format not confirmed here; copy from Chartboost.
- Your file is ready. Copy it or download it, then upload it to the main folder of the website you put in your Play Store listing, so it opens at
https://yoursite.com/app-ads.txt. - Check it after uploading: Check my setup →
