Hello everyone,

Recently joined WHT. SEO is not my area of expertise and would appreciate some input on this topic.

We are currently hosted on Amazon's EC2 webservice, people more familiar with EC2 will know that you can add/restart instances (servers) all the time. The downside of doing that is that you are assigned a new IP Address each time.

So in our case, if we restart our Proxy server, the website gets a brand new IP Address. My question is will this have an impact on the way search engines rate a site ? If yes, what are my options ?

I am sure many folks out there would be in a similar situation and would really like to hear how you go about mitigating an IP Address change.

Thanks for all your inputs.

cheers,

SE will care only the domain name not IP. in shared hosting its happening but no problem at all.........

Interesting, not exactly sure about the impact of a frequently changed IP, but google did mention IP is one of the factor for determining local search ranking.

Yeh i have read that soon google will be looking at how many time dns servers ips have been changed to determine the reliability of a site, so maybe its a factor to keep in mind no one knows for sure yet if google take it to consideration or ever will

fyi - an instance will only loose its ip if you terminate it... rebooting the instance won't effect the ip.

i don't think you'll have issues with seo - maybe if the ip was changing constantly. look in google's and yahoo's faqs... might find an answer there.

do you use a dynamic dns service? you might have better luck looking for the answer from people using that.

Changing IP have effect on stability and credibility. If you are optimizing for Google then this will surely effect your website ranking. Google use IP to detect linking scheme if you have many websites linked to each other and hosted on the same hosting then you won't be getting good position on SERP.

Dynamic IP's are nothing new to any of the larger search engines. As long as they can reach your website via the url, they can index and rank it accordingly.

I have yet in 9 years to see a proven case of this hurting anyones website or rankings.

In real world would you do business with the company that change their office location from one place to another from time to time? I admitted that nobody know the algorithm behind this but Google did mention about taking IP as one of the factors to determine ranking didn't they.

Dynamic IP's, while not a wonderful thing, are nothing new. There are a number of ISP's that will not give you a static iP address, and if you host your own webserver, you really have no choice. Does that make them worth less? No. Does that make users think less of them? Doubtful, as 99% of the users will never even see the underlying IP address, only the domain name.

Not that I have seen, and I even read the (mainly) worthless patent applications.

I didn't said anything about worthless and I didn't said anything about users thinking less please get to the point. I said that it have effects on ranking because Google said that they take IP as one of the factors in their calculation and please stop arguing with me because it is no good for readers.

IP address has zero effect on ranking.. I used to own a hosting company and have moved more than my fair share of websites over the years.. Never once has a change of IP address, in itself, caused an issue for anyone..

Having the site go down for three days during a move, maybe a little bump.. Changing ownership names in the dns / whois records, possibly.. But never once with just an IP change..

The only thing IP addresses are used for, and even this isn't 100%, is geo targeting.

please stop arguing with me because it is no good for readers.

No problem, just stop saying things as fact when you have no idea what you are on about :)

Changing IP is not like changing business office at all, and there are webhosts who provide clusteres sttups where your IP changes anytime.

One possibility is if one of IP you change is blocked in google because of black practices like cloaking etc. then you come into problem.

Hello everybody,
I'm newbie here, but have desire to stay for a long time :)
IP address have no effect to SEO ... I was make one experiment with 10 site hosted on one shared hosting plan . They transfer everything, the link authority...all.
In this 4 months the only thing who I can not determine is the TBPR tranfer between the sites.

The OP is asking about changing IP address of a domain, not hosting multiple domains on an account, both are different things and have different scopes.

with this case I want show and say to w3kit, IP address have influence over SEO

What do you base that on Kalin?

ops ... I missed on NO ... My previous post must be:
with this case I want show and say to w3kit, IP address have NO influence over SEO
My statement base on one experiment with 10 sites (a part of them have a content with same subjects and another have different), placed on one shared hosting plan, one IP and links between them. They tranfer link authority, they exercise influence over the ranking after three-four months.
I can not say what is PR transfer between them at the moment, but this will be clear after next google PR update :)

P.S. sorry, about my mistake in previous post
