bid-matrix.com's sellers.json looks incomplete: it lists 206 sellers, while app-ads.txt files name 257 other bid-matrix.com accounts it does not list. A line it does not list may be a seller the network never published rather than a stale line, so we show no verified or not-listed share for it.
Apps and lines are recounted every 10 minutes. The sellers.json breakdown and the directory ranking are as of , recomputed daily. sellers.json last read 10 October 2026. The supply path score sums up how short and clean the declared paths are, 0 to 100 (how it is computed).

Common errors with bid-matrix.com lines
-
Seller ID not found
8,959 lines
Ask bid-matrix.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
428 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.

Questions about bid-matrix.com
How do I add bid-matrix.com to app-ads.txt?
Add one line for each account bid-matrix.com gives you: "bid-matrix.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 bid-matrix.com. The account ID must be the seller_id bid-matrix.com lists for you in its sellers.json; bid-matrix.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 bid-matrix.com publish a sellers.json?
Yes. Its file at https://www.bidmatrixdsp.com/sellers.json listed 206 sellers when we last read it on 10 October 2026: 139 publishers, 62 intermediaries and 5 listed as both; 0% are confidential.
How many apps declare bid-matrix.com in app-ads.txt?
104,030 apps in Stoqlab's data (delisted apps included) declare bid-matrix.com: 10,957 with at least one DIRECT line and 101,126 with at least one RESELLER line, across 13,122 app-ads.txt files. Counts are recomputed daily.
Why do bid-matrix.com lines fail verification?
Of 25,776 lines naming bid-matrix.com, 8,959 contradict its sellers.json. The most common case is "Seller ID not found" (8,959 lines): Ask bid-matrix.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.
