I used to have a site which was focus on providing free WordPress Themes for various niches. At that time, I didn't know how to monetize the site and it was just my hobby. However, I want to launch this kind of site again because it's my hobby, and I like doing it during my free time. Now, the thing is how to make money with it? Because adding affiliate links to another premium theme sites such as ThemeForest, ElegantThemes and similar sites was not working, I'd like to know if there is/are any more monetization method(s) beside that.
