Questions about ad.plus
How do I add ad.plus to app-ads.txt?
Add one line for each account ad.plus gives you: "ad.plus, YOUR_ACCOUNT_ID, DIRECT". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through ad.plus. The account ID must be the seller_id ad.plus lists for you in its sellers.json; ad.plus will give it to you. Put the file at the root of the domain named as your developer website in the App Store and Google Play listings.
Does ad.plus publish a sellers.json?
Yes. Its file at https://ad.plus/sellers.json listed 1,048 sellers when we last read it on 9 October 2026: 1,048 publishers, 0 intermediaries and 0 listed as both; 0% are confidential.

Why do ad.plus lines fail verification?
Of 820 lines naming ad.plus, 487 contradict its sellers.json.

Buyers that check sellers.json drop these paths.
What is the difference between DIRECT and RESELLER?
DIRECT means the publisher owns the account; RESELLER means an intermediary sells the inventory on the publisher's behalf. DIRECT lines should match a PUBLISHER entry in the network's sellers.json, RESELLER lines an INTERMEDIARY entry.
