Money with Free Sites?

[LD]

My sales seem to come in spurts. I'll get 4 or 5, and then have a long dry spell. I've done a few AVS too, without much luck. I've noticed too that some of my submissions do not get listed till weeks, sometimes months after the initial submission which adds more delay to the whole process.

I have thought about going back and doing some mirrors on my old sites to spread them around a little more, since now I have a better feel for where the best traffic originates. Would this be worthwhile?
