Okay, so besides the domains that make me solid profits through domain parking, I have around a 100 low-mid quality domains sitting around. I've just started in the IM game, and want to make full use of these domains. The trouble is that these are all random domains that don't focus on any particular niche, so building niche sites on them would be a waste of time. I'm thinking of using them for backlinks to my money sites. But developing 100 domains is of course a problem. What would you recommend I do with them? Set up auto blogs on each and link back to my main money sites? Will this help my rankings at all? Or should I set up auto blogs, set up Adsense, and try and earn a few bucks?
