I have a few affiliate links in my No CS Degree articles that pay me 40% and this was my first time where I had a rush of payments go through. I actually had a lower month in terms of revenue in November.
So this was a great way to start December 😀
I've also got an affiliate link for an algorithms interview preparation product which is made by a Google engineer I interviewed in August. I've been adding that link to the end of some of my other articles as well.
