Questions about mobfox.com
How do I add mobfox.com to app-ads.txt?
Add one line for each account mobfox.com gives you: "mobfox.com, YOUR_ACCOUNT_ID, DIRECT, 5529a3d1f59865be". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through mobfox.com. The account ID must be the seller_id mobfox.com lists for you in its sellers.json; mobfox.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 mobfox.com publish a sellers.json?
Yes. Its file at https://uis.mobfox.com/sellers.json listed 579 sellers when we last read it on 9 October 2026: 542 publishers, 32 intermediaries and 5 listed as both; 0.2% are confidential.
How many apps declare mobfox.com in app-ads.txt?
66,286 apps in Stoqlab's data (delisted apps included) declare mobfox.com: 5,715 with at least one DIRECT line and 65,759 with at least one RESELLER line, across 7,725 app-ads.txt files. Counts are recomputed daily.
What is the certification authority ID for mobfox.com?
62% of the app-ads.txt lines naming mobfox.com carry "5529a3d1f59865be" 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.
Why do mobfox.com lines fail verification?
Of 12,748 lines naming mobfox.com, 4,407 contradict its sellers.json. The most common case is "Seller ID not found" (4,311 lines): Ask mobfox.com 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.
