When I logged into my Google AdSense account yesterday, I saw a red warning saying that one or more of my websites does not have an ads.txt file. In this tutorial, you’ll learn how to solve this problem. How to fix an ads.txt alert in Google AdSense account

Note! These instructions describe how to create an ads.txt file for Google publishers. Non-Google publishers should contact their SSP or exchanges.

This article is about the ads.txt file. For information about the app-ads.txt file, I recommend reading another article.

What causes this issue

Earnings at risk - One or more of your sites does not have an ads.txt file. Fix this now to avoid severe impact to your revenue.

In my case, the above message appeared spontaneously on June 6th. This message is self explanatory. It means that we have not added an ads.txt file to one or more of our websites. Google strongly recommend that we use an ads.txt file. It can help buyers identify counterfeit inventory and help us receive more advertiser spend that might have otherwise gone toward that counterfeit inventory.

«Authorised Digital Sellers», or «ads.txt», is an IAB initiative to improve transparency in programmatic advertising. Publishers can create their own ads.txt files to identify who is authorised to sell their inventory. The files are publicly available and crawlable by buyers, third-party vendors, and exchanges. You can learn more about an ads.txt file at the following links:

Now we know what caused this red warning.

How to solve it

To solve this problem, we need to add an ads.txt file to the root level of our domain (for example, https://example.com/ads.txt). Now, step by step guide.

Create a text (.txt) file named ads.txt on your computer (we will move this file later) by using any text editor.

Note! If you have the Mac computer then just use the TextEdit app that ships with every macOS in order to create this file. Save the file in the .txt format.

Include the following line in the ads.txt file you just created:

google.com, pub-0000000000000000, DIRECT, f08c47fec0942fa0

Important! Make sure you replace pub-0000000000000000 with your own publisher ID.

Place your ads.txt file to the root directory of your website. Make sure you save the file.

You can do this by using cPanel or accessing your server via FTP or SFTP. If you aren’t sure how usually your web hosting provider will have instructions somewhere on their website.

Finally, you can visit your website and verify that you have the ads.txt file now. For example, https://example.com/ads.txt.

Conclusion

That’s it, you’re done.

Changes require some time and do not take effect immediately. Patiently wait for Google AdSense to cheque if the ads.txt file is added correctly. In my case, it took 6 days.
