An abbreviation for 'Authorised Digital Sellers', ads.txt files are the online advertising industry's latest tool in the battle against ad fraud. The purpose of ads.txt files is to give advertisers and advertising networks the ability to verify who is allowed to sell advertising on your website. This process is automated using 'crawlers', which are automated computer programs which index ads.txt files, much like a search engine. This information is then used by advertisers and ad networks, with this process normally being automated as part of the ad buying process.

The ads.txt Guru blog is frequently updateed with the latest news and useful articles about ads.txt files, along with the latest developments at ads.txt Guru.
We are very pleased to announce two new features to simplify usage of the ads.txt Guru system for both publishers & ad networks.
ads.txt Guru provides a powerful collaboration system which enables ad networks and publishers to fully automate their ads.txt file management. In this article we will demonstrate how this collaboration works from the perspective of the ad network managing their ads.txt records within publisher ads.txt files.
We're very excited to announce a significant update to the ads.txt Guru system.
For those of you who don't want to connect your FTP account, don't use WordPress, and simply don't want the hassle of uploading your ads.txt file, we can now host your ads.txt file for you. Once enabled all you need to do is set-up a redirect from your ads.txt file and we will handle the rest.
Today we have applied the first major update to the ads.txt Guru system since it launched, with the addition of flex records for collaborators.
Flex records are essentially data records, but with the benefit that a unique publisher ID can be set for each domain the group is collaborating with. This allows a collaborator to create a single group which provides different ads.txt records for each domain which is collaborating with the group, therefore eliminating the complexities associated with creating unique ads.txt files for individual publishers.
ads.txt files are very flexible, and so long as you follow the basic syntax and formatting it really doesn't matter how you include your data, but that doesn't mean it's not a good idea to maintain some structure and consistency in your ads.txt files, if not for the crawlers but for your own sanity when you come to update them.
