Google admob app-ads.txt

Today, we will talk about a necessary industry-standard called app-ads.txt and what Google Admob is doing to support it.


Welcome back to another Google Admob tutorial. We’ll cover what app-ads.txt is all about, its main benefits, and implementation guidelines to help you adopt it.

So, what exactly is app-ads.txt?

It’s a measure released by the IAB tech lab that blocks unapproved or domain spoofed app inventory from being transacted via mobile, connected TV, and other devices.

In other words, it represents a simple process for app publishers to disclose who is authorized to sell or resell their digital advertising inventory publically. App-ads.txt is an expansion of the original ads.txt standard, and the IAB was first published in 2017.

The ads.txt measure is one of the most prosperous industry standards and is now universally adopted by web publishers.

So, when should publishers use app-ads.txt?

App-ads.txt aims to address the problem of misrepresented app inventory, also known as spoofing. The app-ads.txt files are publically reachable and crawlable by exchanges, supply-side policies, SSP, and other buyers and third-party vendors.


We strongly encourage you to adopt app-ads.txt to help protect your inventory from authorized buyers and prevent counterfeit inventory from damaging your brand.

Now, how can pubs implement app-ads.txt?

All you need to do is create an app-ads.txt file and publish it to the developer website that you used in your app store listing. Before we dive into the step-by-step instructions, note that it is crucial to implement the standard correctly, as errors could interrupt ad serving.

To ensure proper implementation, follow these steps.

1. Firstly, create the app-ads.txt file using the Authorized Sellers for Apps specification provided by the IAB.

2. After that, sign in to your AdMob account 

3. Click ‘Apps’ in the sidebar.

4. Click ‘View all apps.’

5. Click the app-ads.txt tab.
