Your ads.txt file is composed of the following parts
For example: google.com, pub-XXXXXXXXXXXXXXXX, DIRECT, f08c47fec0942fa0
Where:
- “google.com” is the advertising system domain
- “pub-XXXXXXXXXXXXXXXX” is your unique publisher ID
- “DIRECT” indicates a direct business relationship
- “f08c47fec0942fa0” is Google’s AdSystem ID
So to create your own ads.txt, all you need to do is go to your account information page (Account information – Settings – Account – Google AdSense) and pull your publisher ID and slot it in.
Once you’ve got your ads.txt file set up on your website (I used Ads.txt Manager – WordPress plugin | WordPress.org for this).
When its added in, you can check to see if its showing up properly by visiting website.com/ads.txt (in my case pezant.ca/ads.txt)
Or if you want to, you can also use this tool which works well!
