AdSense ads.txt missing


Seasoned Veteran
Does anyone know what this "error" message is? Currently displayed on the AdSense website and reading the FAQ has just confused me a bit. It says to check the Sites section to see which of my sites have been impacted but I can't see any indication for any of my sites. I've been making a few pennies for the past few days but a lot less than usual so I'm slightly worried.

I'm not sure what the ads.txt file exactly is and what I should put in it.

Any help or an ELI5 would be great :D

Same here I used to have that error lol, BUt I did added the ads.txt and the error got removed. Google always doing something new right?

You got to have an as.tet in your root folder with the following code so that google can read it. the code is displayed on the help page
