Im looking to create a whole heap of mini sites / blogs to link to my money site. These will all be new sites / new domains. Starting from scratch what would be the quickest way to get these sites up to a PR 3-4 ??? What have you done in the past that has worked? I don't want to buy existing random name domains because I want these sites to look 100% legit so I can also offer guest blog opportunities to other sites in my niche. Thanks!
