Parameters - Google Web Master Tools

[DHS_SH]

In Google Web Mastertools you can stipulate which paramters you want the Googlebots to ignore when crawling your site.

This is common place on pages that add some form of parameterisaton to the end of the link when a web user filters the information on a page (eg. on a clothes website someone may filter the products so they only see 'blue' jumpers, rather than 'all')

This is meant to be beneficial as it means Google trawls through less duplicate content.

Having now set this up, what impact will this have on my search results, if any?

Don't get me wrong, I'm not expecting to shoot up to no.1, but will it benefit me in any way?

Hard for me to tell, but with a million pages and facebook and many others adding useless parameters on the end of our URLs, its been a major problem for a few years.

The thing I really dislike about the google interface for handling this is that there is no way to tell them to ignore all parameters. Hopefully, with the number of parameters I've told them to ignore, they just automatically ignore all new parameters.
