ads.txt-for-apps | Ads.txt for Apps (app-ads.txt)

App-ads.txt is a simple solution that gives you complete control of your inventory. By creating a depository of authorized sellers, you can let your buyers identify the programmatic firms that have legitimate access to the inventory.

App-ads.txt will be a text file on the app publisher’s website that declares who is authorized to sell the publisher’s inventory.

How to implement app-ads.txt?

Perform these steps to implement app-ads.txt:

Step 1: Provide developer website URL in the app store

Publishing a website and providing its URL is mandatory for the app’s ad inventory to participate in the authorized seller scheme.

Step 2: Create the app-ads.txt file

Create a .txt file and name it app-ads.txt.

Step 3: Add Entry

Add an entry in the app-ads.txt concatenating the following information. Contact your partner manager for assistance.
