thank for your reply...

Yes I read already about "rel=canonical" but using a CMS like Joomla this is not easy to implement.

For what I understand in this page:

[support.google.com...]

..the fact to set canonical consist to tell Google wath are my preferred URL. But instead to do that I would prefer tell to Google URL I want to NOT be crawled because this seem more logic and easy to implement.

So I have followed Google Webmaster Tools tutorial explained here:

[support.google.com...]

I apply a URL parameters for the attribute "fontstyle" telling this attribute change de way of how the content is displayed to "Other". Then I selected "No Urls". But after many weeks/month I don't see any result and my 404 error increase instead to decrease.. :-(

I analyzed many error 404 page and 90% of them are made because the attribute "fontstyle" is present inside my URL...

Can you tell me why Google continue to crawl that url?

Please other question:

For solve this "fontstyle" problem I wondering if the fact to publish again my "Fontstyle Button" and to apply to that buttons a rel=nofollow OR rel=noindex OR both (if possible but I'm unsure if both are possible) can do the job.

many thank
