sub domains

are they bad for google ranking

[harvey_moon]

Hi all,

I have a domain which will link to three sub domains depending where the user comes from e.g us,uk etc.

does google penalise this for being a redirect?

Each sub domain will have its own home page but all very similar but diffrent countrys info on.

I will only be submiting the main domain for serps as all the sub domains link back to the main doamin to check the users origin.

thanks

Google do this themselves don't they? - IP delivery for country targetting seems okay to me but then I'm hardly an expert.

Anyone have better info to offer?

I use subdomains for one site with no consequences. I have different content areas on them, however, and don't duplicate content. They are all on the same IP, and they don't interlink (except all linking to main domain).

I think if there is anything to be concerned about, it MIGHT be the duplicate content on these different domains, and perhaps interlinking too heavily. I have no experience there.

Google doesn't seem to make the distinction that foo.widgets.com is related to bar.widgets.com simply from the top level domain. They behave the same as foowidgets.com and barwidgets.com would.

Welcome to WebmasterWorld, Harvey!

Seriously, do yourself a favor and try the site search [google.com].

The subdomains [google.com] issue and tons of different aspects has been discussed a zillion times here.

I remember at least half a dozen of dicussions about the multi language subdomain [google.com] question alone.

Also the language redirection [google.com] issue has been covered a few times ...

Don't only optimize for google but also use it. ;)
