Ok hopefully more help with this one.

I have 279 duplicate meta descriptions
115 short meta descriptions

791 duplicate title tags
157 missing title tags

In webmaster tools can someone please tell me how I fix this problem.

thanks

What's the source of this duplicities? Are these pages some products in VM?

It was a mixture of index (original) and SEF URLS that were giving the duplicates also was mixed up SEF URLS that had 3 SEF urls joined together. Also some that had an old flypage mentioned in the URL.

Easy one as it's a VM product from Different categories
Some examples



I got the SEF urls that were joined together fixed, then changed the Robot.txt file to disallow the other URLs and also the parameters in webmaster tools. Cleaned the 301 redirects and went through the duplicates and made active one of every duplicate. So hopefully this will have some effect.
