Google, Say It Isn't So Already

Some web hosting customers, especially those with dubious business plans who have hired SEO witch doctors, request that every web site be placed on a separate IP address. The theory is that Google is likely to discount the links between sites on the same IP address because such sites may be trying to artificially increase their PageRank. It would be silly for Google to do this since there could be hundreds or thousands of unrelated sites that share an IP address, simply because they are customers of the same web hosting company. Nonetheless, this seems to be a widely-held belief.

This is frustrating to those in the hosting business because IP(v4) addresses are a finite resource, and here in North America, requests for new IP addresses for IP-based web hosting must include a technical justification.

Today, Sean emailed Google to ask for clarification. I hope that Google will publicly state that using multiple IP addresses cannot be used to inflate PageRank.

Update (Thu, 09 Dec 2004): Google responds by saying, go ask someone else to speculate.
