Questions about mopub.com
How do I add mopub.com to app-ads.txt?
Add one line for each account mopub.com gives you: "mopub.com, YOUR_ACCOUNT_ID, DIRECT, 74b46c0ea83967ca". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through mopub.com. The account ID must be the seller_id mopub.com lists for you in its sellers.json; mopub.com 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 mopub.com publish a sellers.json?
We could not reach it (last attempt 8 October 2026). Lines naming mopub.com stay unchecked until it answers again.
How many apps declare mopub.com in app-ads.txt?
18,510 apps in Stoqlab's data (delisted apps included) declare mopub.com: 18,050 with at least one DIRECT line and 677 with at least one RESELLER line, across 1,696 app-ads.txt files. Counts are recomputed daily.
What is the certification authority ID for mopub.com?
100% of the app-ads.txt lines naming mopub.com carry "74b46c0ea83967ca" in the fourth field. The field is optional; the IAB Tech Lab ads.txt 1.1 specification says identifiers in sellers.json supersede it, so a missing or different value does not make a line invalid.
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.
