lightad.com

Add one line for each account lightad.com gives you: "lightad.com, YOUR_ACCOUNT_ID, DIRECT, 7a07b764e0bdb717". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through lightad.com. The account ID must be the seller_id lightad.com lists for you in its sellers.json; lightad.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.

Yes. Its file at https://lightad.com/sellers.json listed 32 sellers when we last read it on 9 October 2026: 28 publishers, 4 intermediaries and 0 listed as both; 0% are confidential.

4,920 apps in Stoqlab's data (delisted apps included) declare lightad.com: 1,809 with at least one DIRECT line and 3,972 with at least one RESELLER line, across 188 app-ads.txt files. Counts are recomputed daily.

84% of the app-ads.txt lines naming lightad.com carry "7a07b764e0bdb717" 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.

Of 230 lines naming lightad.com, 120 contradict its sellers.json. The most common case is "RESELLER but publisher" (118 lines): If the account is yours, declare it DIRECT. If a partner holds it, ask lightad.com why the account is listed as PUBLISHER.

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.
