My problem is that Google sees as duplicate URLs. For ex:
http://mysite.com/keyword1/keyword2/
and
http://mysite.com/keyword1/keyword2/?utm_source=rss&utm_medium=rss&utm_campaign=keyword2
In Google Webmaster Tools it says that these two are pages with duplicate metadescription and duplicate title. Is this a major problem???
And if it is what should I do?? I am waiting for an answer. Thank you.
