Publisher and advertising data
Public ad-seller records.
25,309 checked source records
Ad networks publish files listing the sellers they work with. We collected these records, checked their structure and made the snapshot easier to inspect.
One row is a seller ID at one ad network. A business may have several IDs or appear at several networks. Its business domain may differ from the website where ads run. These records describe the ad supply chain; they do not report site earnings.
Collected . This is a dated snapshot. The source files can change.
Use the records
Find a seller in this snapshot.
Look up a business domain or an exact seller ID. The file loads only when you ask. Searches run on this device; they do not visit the domain you enter.
IDs match exactly. A domain search includes that domain and its subdomains. A missing result means no match in this dated snapshot; it does not prove a site has no ad partner.
| Network | Seller ID | Type | Business domain | Source |
|---|
No matching records. Try another network or check the ID. Ask our team to help check it.
What did we check?
- Each published record has a seller ID and a known seller type.
- The network and seller ID together are unique in this snapshot.
- We removed exact duplicate IDs and excluded IDs with conflicting records.
- We cleaned domain formats and left missing or confidential domains blank.
- Personal names, emails and addresses are not republished.
- File hashes let you check that a download matches this snapshot.
How do these files fit together?
IAB Tech Lab’s sellers.json standard describes seller identities in the ad supply chain. Its ads.txt guide explains the publisher’s separate list of authorised sellers. This snapshot reformats the providers’ public records; it does not replace either standard or verify each provider’s claims.
What can you use it for?
Look up how a seller is described by a network. Check whether the record says publisher, intermediary or both. Compare the provider’s source with an ads.txt entry on a website. A listing alone does not prove that ads are active or that a site earns a certain amount.

- A business domain is not necessarily the monetized website. Multiple accounts can belong to one business and one domain can appear in more than one network.
- A record does not prove that ads currently run on a site, that the seller is approved for a different product, or what it earns.
- This is not an RPM dataset. It does not enlarge the separate historical earnings study.
- A structural check validates the captured file, not the truth of every provider statement or independent approval of Plain Reckoner.
