How to handle sitemap with pages using query strings?

[5225Marketing]

Hi,

I'm working to optimize a site that currently has about 5K pages listed in the sitemap.  There are not in face this many pages.  Part of the problem is that one of the pages is a tool where each sort and filter button produces a query string URL.

It seems to me inefficient to have so many items listed that are all really the same page.  Not to mention wanting to avoid any duplicate content or low quality issues.

How have you found it best to handle this?  Should I just noindex each of the links?  Canonical links? Should I manually remove the pages from the sitemap?  Should I continue as is?

Thanks a ton for any input you have!

you have 3 choises ,

1. redirect

2. cannonical links - be careful with this

3. Change in code of your site rel nofollow to this comboboxes/ filters

4. And it is better do not have these liks in sitemap
