Ads.txt on Sevio Ad Manager

Authorized Digital Sellers, or ads.txt, is an initiative by the IAB Tech Lab that helps to ensure that your digital ad space is only sold by sellers you've approved. 

By creating your own ads.txt file, you gain greater control over who can sell ads on your site, reducing the risk of counterfeit inventory being offered to advertisers.

Basically, this file aims to improve the transparency for programmatic buyers and minimize cases of ad fraud.

Sevio Ad Manager prioritizes the integrity of your advertising inventory. That's why using ads.txt is mandatory on our platform (currently on desktop only, but in the future it will also be required on app inventory).
