Introduction to app-ads.txt support

Implement the app-ads.txt file on your developer website to declare authorized ad sellers, enhance transparency, and prevent revenue loss from unauthorized inventory.
Read time 1 minuteLast updated 9 hours ago
The app-ads.txt file is an Interactive Advertising Bureau (IAB) standard for mobile apps designed to prevent ad fraud by verifying the legitimacy of sellers authorized to monetize a publisher’s inventory. It protects advertisers from buying invalid traffic and gives greater assurance that their purchases are legitimate impressions from authorized sellers. The 
app-ads.txt
file improves publishers’ ad revenue potential since many advertisers prioritize inventory with verified 
app-ads.txt
files. It also helps avoid revenue loss by blocking unauthorized or misrepresented domains. The 
app-ads.txt
file provides the same functionality as ads.txt, except that developers must host the 
app-ads.txt
file in the root of the developer website. Brand advertisers and demand-side platforms (DSPs) scrape this file and cross-reference it when they buy ad inventory programmatically by using exchanges, supply-side platforms (SSPs), and ad networks. Implement 
app-ads.txt
support to combat fraud and create more transparency for mobile advertising. In return, app developers connect with more premium advertisers and higher revenue. Here are additional reasons to implement 
app-ads.txt
support in your mobile app:
  • DSPs use this file to understand the supply chain of inventory they buy.
  • Some DSPs and brand advertisers only buy from authorized inventories from developers who correctly implement this file.
  • Developers who properly declare their authorized sellers help advertisers reduce the risk of counterfeit inventory, which directs more advertising dollars to quality developers over time.
Important
Unity Ads requires you to implement 
app-ads.txt
to display banner ads. If you don’t implement 
app-ads.txt
, banner demand is significantly decreased.
