Hi, Does 200 PR5 links from same ip are stronger han 10 PR5 from different ip's (both sites are not related to the sites theme)? Ive seen a site with a total of 230 links : 200 links from same ip and 30 links from related websites ranked very highly for a competitive word Sitewide links were place in 2006 and google started in August 2005 roughly with the google bowled system..
Well the relevancy of the linking pages to your site is most important, but generally speaking I'd take multiple IP links 9 out of 10 times.
