This is not true. It's been well documented that PageRank uses a number of metrics, probably the most important of them (in terms of ranking) being the number of links to a page or site (and I believe, the PageRank of the pages/websites those links come from). One of my websites has consistently been in the top 10 or at worst top 20 results when searching for the word "megapixel" despite the word only appearing on the resulting page about 4 times - if it was simply content based there's no way that site would be ranked so highly.
Matt Cutts from Google has publicly stated this to not be true; if it is true and he was lying, then everyone hosted at a large provider would be penalized for doing so from an SEO perspective since the likelihood of being on a 'close' network to similar content would be high when you've got hosts running hundreds of thousands of name-based sites off one /24. Actually he stated this to not be true in response to a thread I started on this list about this subject several years ago when I was complaining about Google causing IPv4 exhaustion due to people asking hosts, with some willing, to give them a bunch of IP's on different /24's for SEO purposes when there is no technical justification for it. We've had customers leave and go elsewhere after refusing to give them IP's they didn't need because they were convinced by some SEO 'expert' that they need a bunch of doorway sites on a variety of /24's. If someone is willing to leave their host over that, there are certainly going to be hosts willing to dish up IP's for SEO reasons, and the waste of addresses continues. David
