Checking your ads.txt is correct, line by line

Checking your ads.txt is correct, line by line

ads.txt is a public file listing who's allowed to sell your ad space. Buyers check it before bidding.

The audit:
— 1. Visit yoursite.com/ads.txt in a browser — it must load, plain text, no errors.
— 2. Confirm every demand partner gave you their exact line to paste.
— 3. Check there are no duplicate or expired lines from old partners.
— 4. Match each partner's seller ID character for character.
— 5. Re-upload and wait — buyers re-crawl it every day or two.

A missing line means some buyers silently refuse to bid on you.

In plain English: make sure the public 'who can sell my ads' file loads and lists every current partner correctly.
