Session/Banner Id's

[Mary)]

Hi,

Got a problem with Yahoo where one of my pages has been indexed with over 300 pages in google all with the banner tags i.e. domain.name/btag?

Now I know this poses a massive problem with regards to duplicate content.
It's an ASP page with a submit form on it...

Now unfortuantely I have loads of content on that page which has good rankings in Google. I don't want to exclude that page using a robot file or anyting for that matter.

How do I prevent Session Id's, Banner Tags from being indexed?

Thanks

Can you post one of the urls so I can see exactly what you are talking about.... If you are worried about it getting indexed, you do not have to post an active link.... Just un-select the checkbox for "Automatically parse links in text"
