## Why ads.txt Matters

ads.txt files prevent ad fraud by declaring which advertising platforms are authorized to sell a publisher's inventory. Errors in ads.txt files cause programmatic ad exchanges to reject valid inventory, resulting in lost revenue. For a publisher doing $10,000/day in ad revenue, a single ads.txt error can cost thousands in lost income.
