Ad Tech’s Supply-Chain Auditor

Field notes

The analyzer reads a publisher’s ads.txt and app-ads.txt, then checks each declared ad-system account against the corresponding sellers.json record. Its status model distinguishes missing accounts from domain and seller-type mismatches, while also preserving malformed lines and web/app inconsistencies as separate findings. Batch mode accepts domain lists and is described as capped at 25 domains per run. The page notes that results are point-in-time snapshots because these files change frequently, and that some valid sellers.json files may live on a different subdomain.
