Playbook: audit your sellers.json before a buyer does

Playbook: audit your sellers.json before a buyer does
Watching: DSPs now flag mismatches between your sellers.json and what's declared in ads.txt. Run this monthly.

— Pull every seller_id you appear under across SSP sellers.json files
— Confirm each maps to a live DIRECT or RESELLER line in your ads.txt
— Flag any is_confidential: 1 entry you didn't request hidden
— Cross-check domain field matches your actual root domain, not a subdomain typo
— Kill seller_ids tied to SSPs you offboarded 6+ months ago

Impact: stale seller chains are the first thing fraud teams demote. sourced
