OWNERDOMAIN and MANAGERDOMAIN in app-ads.txt

Updated Oct 7, 2026 · data from 12 App Store genres · top free + top grossing charts · US · iOS + Android

Short answerOWNERDOMAIN declares the business domain of the company that owns the apps. MANAGERDOMAIN declares the business domain of a primary or exclusive monetization partner of the inventory. Both were added in version 1.1 of the IAB Tech Lab specification to make the file's relationships easier to verify.

OWNERDOMAIN

OWNERDOMAIN=examplegames.com

Buyers can compare this domain with the domain listed for DIRECT accounts in ad systems' sellers.json. It's especially useful when the developer website is a product domain (for example a game's site) while ad accounts are registered under the company's corporate domain.

In this index, 40% of app-ads.txt files declare OWNERDOMAIN.

MANAGERDOMAIN

MANAGERDOMAIN=examplepartner.com

The specification describes it as the business domain of a primary or exclusive monetization partner. Check the specification and your partner's guidance for the exact form before adding it.

Common questions

Neither variable replaces correct DIRECT/RESELLER labels: a seat operated by a partner is still RESELLER, even when that partner is your MANAGERDOMAIN.
