About the Data and Seller Score

This tool provides an independent market-monitoring view of sellers based on publicly available sellers.json data, observed seller/domain changes, internally derived supply-trust signals, and reprocessed, aggregated third-party-derived supply-quality signals. The Seller Score is an estimated market-rank score, not a certification, audit, endorsement, compliance finding, fraud determination, or guarantee of commercial performance.

The score is calculated from multiple components, including footprint, directness, transparency, stability, supply quality, and supply trust. Footprint reflects relative market presence in the dataset; directness is based on the share of publisher records versus intermediary records; transparency is affected by confidential seller rates; stability is affected by recent seller/domain movement; supply quality is based on reprocessed and aggregated third-party-derived signals; and supply trust depends on internally derived signals and available coverage.

Metrics such as CSR, DRR, seller counts, domain movement, supply quality, supply trust, and 1d/7d changes are calculated from the data available at the time of the latest update. Results may vary by geography, traffic type, inventory format, integration setup, crawl timing, third-party data coverage, aggregation methods, and normalization rules. A higher or lower score should not be interpreted as a definitive statement that one seller is better, safer, more compliant, or more suitable for every publisher or advertiser.

Company names, domains, and trademarks are used only to identify the relevant sellers, SSPs, and sellers.json sources. All trademarks are the property of their respective owners. Use of a name, domain, or mark does not imply affiliation, sponsorship, endorsement, approval, or partnership with the corresponding company.

Unless expressly stated, no listed seller has paid for placement, influenced its score, or approved this ranking. If you believe any information is inaccurate, outdated, incomplete, or unfairly presented, please contact us so we can review the underlying data and, where appropriate, update or correct it.
