I am honestly stuck, and not because I can't come up with ways in which the websites can make money but which is the best and the easiest to manage. The back story is this, I have these 150 websites spread across 55 C-Class IP's. I am currently closing of doing client work, so I still have these websites left over. In September I am going back to school, so I won't have time to deal with online marketing, at least not that much. But I still want to make some passive income. I'm not sure what direction is best to take to make the most of these websites, there are a lot of them so its difficult to manage, but for the right money I can do it. I was thinking of selling a service such as $250 a month for your website to be put across the entire network, and the links will be main page, so you will keep the page rank and link juice unlike the other link building services. In return I keep sending links to these sites to make them stronger. Let me know what you guys think.
