How to use ads.txt checker safely
Why ads.txt matters
ads.txt is a public text file that lists authorized digital sellers for a domain. Advertising platforms use it to reduce spoofing and confirm which seller accounts are allowed to sell inventory for the site.
For Google AdSense, a common record uses google.com, the publisher ID, the DIRECT relationship, and Google's certification authority ID.
What each field means
An ads.txt record is comma-separated. The first field is the advertising system domain, the second is the publisher or seller account ID, the third is the relationship type, and the optional fourth field is a certification authority ID.
DIRECT usually means the publisher controls the seller account. RESELLER means another authorized party sells inventory. Use the relationship shown by the ad platform, not a guess.
- Advertising system domain: google.com or another exchange domain
- Publisher account ID: the seller identifier from the ad platform
- Relationship: DIRECT or RESELLER
- Authority ID: optional certification authority identifier
Publishing and verification notes
Publish the file at the root of the domain as /ads.txt. After deployment, open the URL in a browser and confirm the file returns plain text with the expected records.
Keep the file small, accurate, and updated when ad accounts change. A malformed or missing line can delay ad verification or cause inventory to be treated as unauthorized.
Why people use this tool
ads.txt checks run locally in your browser. tempboxs does not receive publisher IDs, seller records, or generated lines.
Generate the Google line
Turn a Google AdSense publisher ID into a copyable authorized-seller record.
Review pasted records
Parse ads.txt lines and flag missing fields, invalid relationships, and suspicious Google authority IDs.
Prepare for monetization checks
Use the tool before publishing /ads.txt so ad platforms can verify authorized sellers more reliably.
