Don't get me wrong. It has value as it's a nice term. However it's not one I would want to develop because in my experience people looking for free websites are also looking for free hosting to go with it and they usually don't spend. I would pitch it to big domain companies that provide this.
Perhaps thats true but plenty hosting companies advertise “free websites” and thats the crux of it. If they have advertising on the term already they might be willing to pony up 5k for a lead funnel. 5K equals roughly 10x CPA leads on some of the best hosts via CJ.
