Selling domain names on Flippa is something I saw coming a few years ago. I did some business several years ago on Flippa when I use to build websites, optimize them for the search engines and then monetize them. If you haven’t noticed yet, web properties that earn revenue are a HOT commodity. You could get between 10X and more of the monthly earning revenue if you decide to sell, which is what we did all those years ago.
Flippa wasn’t known for ONLY domains (without a corresponding website) at the time but I remember when I got into domaining thinking of how Flippa would become a platform where domains could be bought and sold, WITHOUT a website.
And now look, Flippa is a pretty popular place for the domain name space.
