Common errors with smartadline.com lines
-
Seller type BOTH
814 lines
The account is listed as BOTH, so sellers.json alone cannot tell a buyer which relationship applies. Nothing to fix on your side; buyers usually look at the seller's domain.
-
DIRECT but intermediary
187 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask smartadline.com to list it as PUBLISHER.
-
Seller ID not found
102 lines
Ask smartadline.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.

RESELLER but publisher
79 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask smartadline.com why the account is listed as PUBLISHER.

Questions about smartadline.com
How do I add smartadline.com to app-ads.txt?
Add one line for each account smartadline.com gives you: "smartadline.com, YOUR_ACCOUNT_ID, DIRECT". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through smartadline.com. The account ID must be the seller_id smartadline.com lists for you in its sellers.json; smartadline.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 smartadline.com publish a sellers.json?
Yes. Its file at https://www.smartadline.com/sellers.json listed 1,351 sellers when we last read it on 9 October 2026: 888 publishers, 8 intermediaries and 455 listed as both; 0% are confidential.
How many apps declare smartadline.com in app-ads.txt?
9,012 apps in Stoqlab's data (delisted apps included) declare smartadline.com: 8,176 with at least one DIRECT line and 4,942 with at least one RESELLER line, across 1,039 app-ads.txt files. Counts are recomputed daily.
Why do smartadline.com lines fail verification?
Of 1,985 lines naming smartadline.com, 368 contradict its sellers.json. The most common case is "DIRECT but intermediary" (187 lines): If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask smartadline.com to list it as PUBLISHER.
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.
