Pagination causing Duplicated content

[sajtfokus]

Hi,
my google webmaster tools (HTML improvements) is showing duplicated title tags and meta descriptions. The most of duplicated content is caused by result pages (for example: mysite. com/results,1-12?/category/subcategory)

I tried to exclude an url parameter "'/results" from google crawler, without success.
Any suggestion?

If you exclude something in the webmaster tools like url parameter, it may take a while until the crawler takes notice about. So, when did you change the url parameter?
