Quick questions as I know little about the hosting structure and ips: I have a main money website and about a dozen secondary websites in the same niche. Would it be worth finding a host that offers the ability to host on different shared IP's just to have more ip's pointing at my money site? Also, was thinking of exchanging links from my secondary sites with other websites in my niche and have them link to my money site instead of the secondary site (All of the sites are PR3.) Does this make sense are is it a lot of work for nothing. Thanks!
on page seo, diversified backlinks, quality content, quality content, and quality content are factors that are so much more important than whether or not the sites are on the same ip address
