Seller ID not found
96,216 lines
Ask taboola.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.
-
Seller type BOTH
457 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
219 lines
If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask taboola.com to list it as PUBLISHER.

Questions about taboola.com
How do I add taboola.com to app-ads.txt?
Add one line for each account taboola.com gives you: "taboola.com, YOUR_ACCOUNT_ID, DIRECT, c228e6794e811952". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through taboola.com. The account ID must be the seller_id taboola.com lists for you in its sellers.json; taboola.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 taboola.com publish a sellers.json?

What is the certification authority ID for taboola.com?
100% of the app-ads.txt lines naming taboola.com carry "c228e6794e811952" 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 taboola.com lines fail verification?
Of 144,482 lines naming taboola.com, 96,535 contradict its sellers.json. The most common case is "Seller ID not found" (96,216 lines): Ask taboola.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.
