Declare authorized sellers with ads.txt/app-ads.txt

About ads.txt/app-ads.txt

You can declare authorized sellers to protect your brand and potentially receive more advertiser spend.

  • Authorized Digital Sellers for Web, or ads.txt, is an IAB initiative to improve transparency in programmatic advertising. You can create your own ads.txt files to identify who is authorized to sell your inventory. The files are publicly available and crawlable by exchanges, Supply-Side Platforms (SSP), and other buyers and third-party vendors.
  • Authorized Sellers for Apps, or app-ads.txt, is an extension to the Authorized Digital Sellers standard. It expands compatibility to support ads shown in mobile apps.

Use of ads.txt/app-ads.txt is not mandatory, but is highly recommended. It can help protect your brand from counterfeit inventory that’s intentionally mislabelled as originating from a specific domain, app, or video. Declaring authorized sellers can help you receive advertiser spend that might have otherwise gone toward counterfeit inventory.
