Welcome to the Q&A Forum

Hi Kami, It's unfortunate, but a number of modern day e-commerce platforms still suffer from poor canonicalisation and multiple URL's. If possible, rather than blocking off access to those queries via robots.txt or meta, I'd start by trying to specify a canonical URL when a query is created. E.G Query: http://www.dellamoda.com/Designer-Accessories.html?sort=title&use_selected_filter=Y&view=all Canonical: http://www.dellamoda.com/Designer-Accessories.html Failing that I'd try to implement a "follow,noindex" meta tag or via x-robots if you're any good with apache. If that's still a no go, then try GWT, Google is getting much better at handling dynamic URL's within e-commerce platforms and you can specify which queries Google should ignore directly within GWT There's a great post on Moz that deals with e-commerce and canonicalisation - http://www.seomoz.org/blog/qa-from-ecommerce-seo-fix-and-avoid-common-issues-webinar - I'd suggest starting there! As a last resort I'd look to block the URL's within robots.txt, but this prevents crawlers from flowing freely within your site and can result in poor indexation.
