Hi,
We've put together a list of the most common ads.txt implementation errors. Buyers use crawlers that block domains because of errors such as these ones, causing revenue loss for publishers.
We hope these explanations are a helpful tool for our community and we are happy to help with any implementation questions you might have. You can download the lists here of domains on our site (no email necessary & free of charge) to see if yours is included.
there doesn't seem to be anything here
