I added an Ads.txt file to this site (see our Ads.txt file). That may sound odd. This site doesn’t have ads! That is true. But I like collecting text files and I learned how to create a properly-formatted Ads.txt file for an ad-free website. For those interested, you can read my new post titled Adding Ads.txt to Website Without Ads on The New Leaf Journal.
I've been tracking the adoption of the OWNERDOMAIN and MANAGERDOMAIN variables from Ads.txt 1.1 since it was released on August, and it's not looking great. Adoption is clearly leveling off at very low rates.
Note that these numbers are for sites that have (app-)ads.txts in the top 100k of the Tranco list. Looking at all sites in Well-Known is even worse.
