Building them is quite nice, but I find that submitting gets to be a bit of a pain.
After building and submitting freesites for eight months I pretty much make a sale per day now, so people do sign up and money can be made.
At various points along the way I try and tweak something, or buy a new domain for a new hub, or start a little webcam site, all gradually building up my little porn-galaxy.
It seems to be working....slowly but surely. Almost every month has seen an increase in traffic & sales all round, but sometimes there are scary weeks where I have doubts. If that happens I just carry on building anyway and maybe concentrate on freshening up my outlook with a new little project.
I'm sure that pretty good money can be made with freesites only, and my current numbers seem to suggest this is possible with enough hard work, but to get enough to live on you probably need to create your own little world of networked freesites/hubs/ etc to keep Mr Surfer in amongst your ads even if he thinks he's already left.
Did that make sense?
