The essential information about ads.txt, its meaning, role and tips on how to implement this simple tool aiming to bring simplicity and clarity to the digital ad market in few quick steps.
What is all the fuss with ads.txt about?
Ads.txt, which stands for Authorized Digital Sellers, is a text file that is implemented in a publisher’s web server to inform those on the buy side about who is selling inventory programmatically. Originally, ads.txt was launched in May 2017 by the IAB to reduce domain spoofing and reselling in the open marketplace.
What main purpose does it serve?
The IAB’s ads.txt was supposed to bring simplicity and clarity to the digital ad market while cutting down on fraud. But so far only a fraction of the world’s top publishers have adopted it.
The file itself is an IAB Tech Lab project developed to eliminate inventory fraud in the digital advertising industry. Just like how robots help search engines understand the contents of a website, the ads.txt helps buyers discover how a website’s inventory is supposed to be sold.
Simply put, the ads.txt lists all the platforms that are authorized to sell the inventory, in terms of all the SSPs used and the specific accounts (seats) run by both the publisher (owned inventory) and resellers (represented inventory) respectively.
