Questions about adster.tech
How do I add adster.tech to app-ads.txt?
Add one line for each account adster.tech gives you: "adster.tech, YOUR_ACCOUNT_ID, DIRECT". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through adster.tech. The account ID must be the seller_id adster.tech lists for you in its sellers.json; adster.tech 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 adster.tech publish a sellers.json?
Yes. Its file at https://adster.tech/sellers.json listed 30 sellers when we last read it on 10 October 2026: 30 publishers, 0 intermediaries and 0 listed as both; 0% are confidential.
How many apps declare adster.tech in app-ads.txt?
8,439 apps in Stoqlab's data (delisted apps included) declare adster.tech: 8,299 with at least one DIRECT line and 156 with at least one RESELLER line, across 723 app-ads.txt files. Counts are recomputed daily.
Why do adster.tech lines fail verification?
Of 764 lines naming adster.tech, 745 contradict its sellers.json. The most common case is "Seller ID not found" (745 lines): Ask adster.tech 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.
