Is Your Site’s IP Address Affect Your SEO and PageRank?

Posted on 21st May, 2007

If you have been doing or reading about search engine optimization (SEO) for a while, you may have came across the idea that it’s beneficial to have your sites hosted across unique IP addresses. Some even suggested that having your sites hosted on different a continent will boost the benefit even further.

There are a lot of ads for directory submitters that claim all the directories are on unique IP addresses to ensure your site enjoys an advantage.

The premise is that having multiple sites hosted on the same IP address will in some way affect the PageRank of those sites negatively. Also, linking between your own domains hosted on the same class C IP addresses might be seen as a spamming attempt by the search engine.

As example if you have two sites hosted on and, they are basically sharing the same Class C IP range. The Class C in this case refers to “195.168.1”

There’s an interesting discussion in regard to the importance of IP address for SEO in Search Engine Watch Forums where someone asks the following

    1. What happens when one web site gets banned and in doing so penalizing the IP ?
    2. Is it fair that a web site using ethical SEO techniques is affected because it is being hosted in a "bad" neighborhood?
    3. Does interlinking websites on the the same shared IP cause search engines to view them as a cluster and consequently loose link weight? i.e. links originating from a single C Block.

Well another person quotes Google as

Actually, Google handles virtually hosted domains and their links just the same as domains on unique IP addresses. If your ISP does virtual hosting correctly, you’ll never see a difference between the two cases. We do see a small percentage of ISPs every month that misconfigure their virtual hosting, which might account for this persistent misperception–thanks for giving me the chance to dispel a myth!"

I’ve been hosting most of my sites on a single dedicated server for years with no problem.

I would say, unless what you do is considered as spamming, Google does not really care about your site’s IP address as far as search engine optimization and PageRank is concern.

    Good that IP is not so important. Otherwise i will have problem because all my sites are on shared servers.

  • wandira says:

    any related articles explaining about linking domains that located under the same class IP is considered spamming by search engine ? Sound weird, cuz we might dont know who linking to our website might host at the same hosting company too.

  • A little spelling error in the title but it doesnt matter anyway! Interesting argument, if your ip effect SEO variables.

  • matter anyway! if your ip effect SEO Interesting argument, variables.
