Check your Ads.txt
Enter a domain name to validate its ads.txt file against the IAB specification and spot errors that cost you ad revenue.
Why ads.txt matters
Ads.txt tells buyers exactly who is authorized to sell your inventory. A broken file means blocked bids, lost revenue and room for fraud.
Full spec validation
Every line is checked against the IAB ads.txt specification — relationship types, account IDs, certification authority IDs, variables and comments.
Revenue protection
Duplicate entries, unknown resellers and typos silently cut into your programmatic earnings. We surface them before buyers do.
Clear, shareable report
Errors and warnings with exact line numbers, a parsed view of every seller record, and a link you can share with your ad ops team.
