Ignore url parameters without the 'parameter=' ?

[Hakkasan]

We are working on an ecommerce site that sorts out the products by color and size but doesn't use the sortby= but uses sortby/. Can we tell Google to ignore the sortby/ parameter in Webmaster Tools even though it is not followed by an = sign?

For example:

www.mysite.com/shirts/tshirts/shopby/size-m

www.mysite.com/shirts/tshirts/shopby/color-black

Can we tell WMT to ignore the 'shopby/' parameter so that only the tshirts page will be indexed? Or does the shopby have to be set up as 'shopby=' ?

Thanks!

Thanks for the response!

Yes, we do want to implement the rel=canonical tag but since we are using Magento to build on we are having some issues. One of the issues is that we have the shirts page with sort features:

www.mysite.com/shirts/shoby/size-m

and then the tshirts page:

www.mystie.com/shirts/tshirts/shoby/size-m

So the problem we're running into is trying to figure out how to write a script to implement rel=canonical so that for the first URL, everything after shirts canonicalizes to the /shirts/ URL, and then for the second URL everything after tshirts canonicalizes back to the /shirts/tshirts/ URL without the /shirts/ rel=canonical overriding it.

As far as I know, you can't do this in Google Webmaster tools.  It would have to be a parameter like shopby= instead of shopby/ as you suspect.

This sounds like a good place to use the rel=canonical tag.  You want those pages to exist, and if people link to them, you want them to pass their link juice back to the /tshirts/ page.  These shopby pages will have a subset of the info on the /tshirts/ page, so Google should respect the canonical tag.

Other search engines beyond Google should respect the canonical tag as well, so that's another benefit to doing it outside of Google Webmaster Tools.
