3 Different Versions Indexed of Same URL!

[Theadjj1]

Hi

Due to my clever previous developer I've found in google analytics that I've ended up with multiple versions of the same pages indexed under a variety of domains.

Question: what's the best course of action, to redirect to the preferred URL? If so how would I do this on an ASP.net site?

http://www.domain.com/\counties\aberdeenshire.asp
http://www.domain.com/counties/ABERDEENSHIRE.ASP
http://www.domain.com/counties/aberdeenshire.asp

Thanks all!

Use the canonical tag and do a 301 redirect to the appropriate URL.

Note: on Windows servers case sensitivity is not recognized, therefore ABERDEENSHIRE.ASP and aberdeenshire.asp are both the same file. On a Linux server case sensitivity is observed and the two examples are seen (correctly) as different files.

This is a problem often encountered when developing on a Windows platform and deploying on a Linux server environment. This can also be problematic if linking in different case sensitivity is used.

If you have a newer version of IIS, 7+ you can do the rewrite rules directly in IIS. If you have IIs6 I would recommend this company, they offer a IIS rewrite module that i've used a few times and it's pretty easy to use. Helicon Tech - IIS modules and ISAPI filters for URL rewriting and search engine optimization Costs a little though.

For more info, google "IIS Rewrite" or "IIS redirect"

In case you have problem with canonical tag and 301 redirect, check out these guides:

you can use htaccess or php redirect to prefered url if you want.

PEOPLE! Please note we're on a Windows server here! ....ASP! The OP's question is pretty clear on this point.

No .htaccess, no PHP, just ASP code and/or ISAPI_REWRITE.

Thank you

Thanks all. Will reciprocate the advice when I can.

Thanks for this but does this case difference affect SEO?
