Why Using A Static IP Address is Benefical... Google Engineer Explains

Aug 10, 2005 • 4:21 pm | comments (12) by twitter Google+ | Filed Under Google Search Engine Optimization

There has been debate for awhile regarding whether or not using a static IP address is better than having a dynamic IP address for your website. By preference myself and I think I speak for many SEO's, we prefer the use of a static IP address when hosting a domain. Most often you can pick up a dedicated IP address from most hosts for a couple extra bucks a month. There are many reasons for this, such as for linking, avoiding penalities on the same IP C Classes blocks, and so on. If you are doing a major site, its just a better idea to have a dedicated IP than a shared one.

I just had lunch with Ian McAnerin which I owe this credit of information to as him as he spent some time talking with Google Engineers last night at the Google Dance.

Generally speaking having a website on a shared IP address will not cause you any harm. You can rank just fine and there is nothing negative about hosting on shared IP's. So don't worry if you site is on it. However what is important to know as I was told is how, Google in particular and possibly other engines look at these static and shared IP. As I was explained when I search engine spider first comes across your site it will parse it with basic HTML 1.0. If its able to do this then it will normally go about getting spidered and indexed. For those sites with a static IP address they will get spidered with HTML 1.0 as its able to resolve the address immediately. If by chance you don't have a static IP address, Google may go about parse the site with HTML 2,3,4 and so on until its able to resolve the address for your specific site. This can take up to 3 months to happen. In the meantime it will use the IP of the main site on this IP, often times the hosts site. It will come back until its able to find your specific IP. During this period of 1-3 months, any links that you build to your site that is found by Google, will get credited NOT to your site, but to the main root site on the shared IP, often times your host site. Quite interesting. As I understand it, after Google is able to correctly identify your site from others, you will get credited for the links. However in the time period of limbo between that, another site will be getting credit for your links. Something which you probably don't want to happen. Interesting.

That was very valuable info - hope that the engineer is correct - Matt Cutts should validate this on his blog - so at least there would be some debate on whether this is technically accurate

What a load of utter crock. Mixing static and shared IPs, mixing html and http, I assume you were only able to write down every other word the "GE" said, it would be embarassing if he really said all of that (and I'd have to sell all my G-Stock right away). :-(

Thanks for the clarification as there is still debate about whether or not to use a static IP address. M.

Call me a skeptic, but I trust no single corporate employee for perfectly accurate info. I called my cell phone company last night, and in five different calls got wildly different info each time. And this was basis stuff, like "*611". I want proof, not an anonymous engineer.

static ip address is more reliable as compared to dynamic

Google not spending all of its time on one client's multiple IP addresses? I don't believe it...

Garbage. HTML is completely different than HTTP which is how the headers are sent from a spider or a browser (which would contain the host/url) and is what any web server uses to produce the site on a shared ip. HTML version has nothing to do with anything and HTTP 0.9 (I think the oldest version used, from 1992) still used hosts OR ips. Google would never choose to use ip over domain as it would make for a bad search engine which we all know it's not.

Really??? Look at the date of the article, Aug 10, 2005. I am pretty sure this may have been accurate 6 years ago, but I am sure it has been fixed.
