Introduction To successfully monetize your supply, it is essential to properly set up and maintain your ads.txt and app-ads.txt files. These files establish transparency in programmatic advertising by allowing publishers and app developers to declare authorized sellers of their ad inventory. Amagi supports content partners in implementing these files correctly to protect revenue and enhance trust in the digital advertising ecosystem.

Step 1: Prepare Your Website A primary developer website is crucial for third parties to access information about your content. This website should serve as the central location for your ads.txt file. If you own multiple content-specific domains, those can reference the primary developer website’s domain as the managerdomain in their ads.txt files to streamline monetization rights.

Step 2: Create Your Ads.txt File

  1. Open a text editor and create a new plain text file named "ads.txt" (this exact naming is required for detection by buyers).
  2. Copy the ads.txt contents from the Connect UI under Connection Action and paste them into your file.
  3. Ensure that each authorized seller entry follows the format:
    • Ad System Name, Publisher/Account ID, Relationship Type (DIRECT or RESELLER), TAG ID (optional)

Step 3: Host the Ads.txt File

  • Have your web developer upload the ads.txt file to the root directory of your primary developer website.
  • Example URL format:
    https://www.wsbtv.com/ads.txt
  • Enter the ads.txt URL in Connect at the channel level for content partners.

Step 4: For Content Providers Using App-Ads.txt If you are a content provider, request that the platform add the following record to their app-ads.txt file:

inventorypartnerdomain=replaceme.com

(Replace replaceme.com with the domain where your ads.txt file is hosted.)

Step 5: Adding Entries to Your Ads.txt File Include the following lines in your ads.txt file:

amagi.com, XXXXX, DIRECT  (Replace XXXXX with your Monetization ID)
inventorypartnerdomain=amagi.com
