Validate sellers.json: JSON structure, version 1.0, seller fields, and reciprocal ads.txt / app-ads.txt checks by Adtimizer. Adtimizer's sellers.json validator gives any ad system's sellers.json an instant health check. Open a sellers.json page and the extension automatically: • Confirms it's valid JSON • Checks the version is "1.0" • Validates every seller — seller_id, seller_type, and name/domain unless confidential • Flags duplicate seller IDs • 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 runs a two-way cross-check against ads.txt / app-ads.txt: which sellers aren't authorized back in publishers' ads.txt, and which ad-system IDs publishers declare that aren't listed in the sellers.json. Built by Adtimizer — the transparency layer for programmatic revenue. https://www.adtimizer.co
