Questions about redmob.io
How do I add redmob.io to app-ads.txt?
Add one line for each account redmob.io gives you: "redmob.io, YOUR_ACCOUNT_ID, DIRECT". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through redmob.io. The account ID must be the seller_id redmob.io lists for you in its sellers.json; redmob.io 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 redmob.io publish a sellers.json?
Yes. Its file at https://dashboard.redmob.io/sellers.json listed 173 sellers when we last read it on 9 October 2026: 63 publishers, 92 intermediaries and 18 listed as both; 0% are confidential.
How many apps declare redmob.io in app-ads.txt?
27,002 apps in Stoqlab's data (delisted apps included) declare redmob.io: 7,139 with at least one DIRECT line and 26,664 with at least one RESELLER line, across 2,132 app-ads.txt files. Counts are recomputed daily.
Why do redmob.io lines fail verification?
Of 5,274 lines naming redmob.io, 446 contradict its sellers.json. The most common case is "Seller ID not found" (446 lines): Ask redmob.io for the account ID it lists for you in its sellers.json, correct the line, or remove it if you no longer work with them. 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.
