hey guys., im looking at creating a network of blogs in similar niches. the thing is i would obviously like to link blogs together....but i cant afford 10 different hosts on 10 IPs. is it pointless to link the blogs if they are on the same IP? what if i linked through a structure of free sites e.g. blog A---->squidoo site--->hubpages site--->blogger blog---->blog B would this work? also is it pointless in me doing link exchanges between the blogs...or should i just have one way links? does google automatically assume that link exchanges are obvious agreements between two sites to link together?
