So I am still in the process of trying to learn all this SEO stuff, and am about to start building web 2.0's for backlinks to my sites. My question is, are private proxies or a VPS completely necessary to do this? And when I am writing these articles my goal isnt to rank them right? So I dont have to worry to much about on-page SEO and all of that? Any info on web 2.0's in general would be great guys. I really need to get this started up.
