Ads.txt (Authorized Digital Sellers) is an industry-standard initiative developed by the IAB Tech Lab to enhance transparency in programmatic advertising. It allows publishers to publicly list approved ad sellers, ensuring that only legitimate partners can sell their ad inventory.
By implementing Ads.txt, publishers can prevent unauthorized reselling, protect their revenue, and build advertiser trust by guaranteeing that ads are purchased from verified sources. Itโs a simple yet powerful tool to combat ad fraud and create a more secure digital advertising ecosystem.
๐จ The Problem: Unauthorized resellers can misrepresent your ad inventory, leading to revenue leakage, reduced advertiser trust, and overall market inefficiencies.
Without Ads.txt, bad actors can exploit the system by selling counterfeit inventory under your name, damaging your reputation and diminishing your earnings.
โ The Solution: Ads.txt serves as a protective measure, ensuring that only officially authorized partners can sell your ad space.
By implementing Ads.txt, publishers gain greater control over their inventory, enhance transparency in the supply chain, and create a more trustworthy environment for advertisers.
Ads.txt is a simple text file stored in your websiteโs root directory (example.com/ads.txt
). It lists trusted ad platforms that are authorized to sell your inventory.
