My website I hate the most makes me the most money
I started a few different websites, all of which I cared about at some point. After awhile I lost interest in really developing a specific one - and it has remained untouched for awhile now. Ironically enough, it is the site that is earning me the most clicks (which ends up being $1 a day, hah.) and the most traffic. If it's performing like this with no nudging, I can only imagine how it would perform with effort.
Have you ever purchased a website with little to no expectation, but still made more money from it than other websites with adsense?
