Mutiple sites, one IP address
How does Google handle it?

 7:29 pm on Feb 5, 2004 (gmt 0)

I know this has been discussed before but cant find the threads...

I want to set up multiple dynamic sites, using different domain names but the same underlying database, and using the same IP address..

I know Google can cope with this, cos I've seen it do it... but is there any penalty?

No penalty is applied. Unless of course you set 10 000 domains and create a link farm.

okay,but I think interlinking the domains will be ignored cause they are all on the same IP?
I could be that there is a penaly for interlinked domains on the same IP. I tested it but I am not sure whether links are ignored or there is a penalty applied.
Just another question:
A competitor setting up 10000 Links to my site from a domain can't hurt me, can it? Since his domain is in a completley other IP Range I could benefit from it, could I?

I guess this could be a good idea, since presumably I would be bundling the benefits (traffic, PR...) of all my sites.

We have the exact setup as you, and we ARE getting backlinks counted by google to each other...

do you mean you have multiple sites on one domain linked together and you get the backlinks counted by google? Maybe they do not count but you don't know.
They could show them but not count. Do you have more links from sites not maintained by you or more links from sites of yourself?

I'd feel free to do this. Lots of ISPs do this to save IP address space. There's nothing wrong with it, and we handle virtual hosting like this just fine, assuming that an ISP configures it correctly. As long as you can surf to the domain with your browser, it should be fine for Googlebot to find it.

(If you want to get way technical, HTTP 1.1 is what allows a spider to do this. Part of an HTTP 1.1 request is that the browser or spider tells the web server which host they're expecting to see. That's what allows the web server to know which content to dish up.)

I have 300 city guides, all have their separate domain names and all on the same IP. Only the cities that are close to each other link with each other. This is also for user functionality, if you are in our Indianapolis site, you may also want to visit Louisville.

I have been doing this for 3 years with no problem and no penalties. I have have also played by the rules and no cheesy spamming or SEO tricks.

Over 3 years, I have grown from 1000 visitors a month to now 200,000 last month

Does this sound right GoogleGuy, or have I just been lucky in not getting a penalty?
