Add Your Personalized Code Snippet

For the app-ads.txt setup, you must ensure to:

  • Use InMobi's personalized ads.txt entries.
  • Add business/payment info to generate entries. For more information, see Payment Settings.
  • Append entries to your ads.txt file.

Follow the instructions below to get your personalized ads.txt entries, which include your InMobi payment ID:

  2. Navigate to My Account >> Manage App-ads.txt.
  3. Scroll down and download the app-ads.txt file.
  4. Post the file in your website's root directory.
  5. Ensure correct formatting and line breaks after updating InMobi’s entries into your ads.txt file.

Publish App-ads.txt File on Developer's Website

InMobi's app-ads.txt crawler locates your file using the developer URL from your app's Google Play or Apple App Store listing. Per app-ads.txt specs, the crawler checks the file at:

  • https://<<hostname>>/app-ads.txt
  • http://<<hostname>>/app-ads.txt

Determine the hostname from your app's developer URL. It's the website's root domain or, in specific cases, a subdomain, as explained below.

Refer to the table for examples where the InMobi crawler checks for an app-ads.txt file based on different developers' website root domains.

If the developer website is: Crawler looks in the following order:

The app-ads.txt specification outlines rules for subdomains. Crawlers will explore up to five redirections within a subdomain and one outside the root domain.

To verify correct publication, ensure the app-ads.txt URL displays its content when accessed through your web browser. If it is visible in your browser, crawlers will probably locate it successfully.

Ensure Crawlable App-ads.txt File

Ensure the app-ads.txt is accessible via both HTTP and HTTPS.

Check Verification Status of App-ads.txt File

Monitor your app-ads.txt files in your InMobi account:

  1. Log in at
  2. Navigate to My Account on the left menu.
  3. Select Manage App-ads.txt.
  4. After you add the with seller information, you can view the verification status loading below.

If your file wasn't located or verified, review the details in your InMobi account or explore troubleshooting tips for app-ads.txt issues.


If you've recently updated your ads.txt file, it may take at least 24 hours for the crawler to display the latest verification status.

First-time Setup Process

Upon creating your account on InMobi and establishing your inventory, access the verification status through My Account >> Manage App-ads.txt. Activation of the InMobi crawler occurs once any of the added apps has generated 10 thousand bid requests.
