About Adtimizer — ads.txt analyzer

Adtimizer's ads.txt analyzer gives you an instant health check on any ads.txt or app-ads.txt file. Open a publisher's ads.txt or app-ads.txt page and the extension automatically: • Validates the file structure against the IAB ads.txt spec • Flags duplicate entries • Detects unknown / unrecognized ad systems • Gives the file a 0–100 health score All of this runs locally in your browser — no data leaves your device. Want more? One click on "Deeper analysis" cross-references every entry against sellers.json data to surface unverified sellers, DIRECT/RESELLER type mismatches, and confidential records. Built by Adtimizer — the transparency layer for programmatic revenue. https://www.adtimizer.co
