Why does pagination create duplicates in Google's results?
This is definitely bad for SEO.

You need to set related links on the each page of the view so that google doesn't crawl all of the variations via parameters. Example:

&lt;link rel="next" href="http://example.com/view?page=2"&gt;


Apparently the metatag module will help with this, or you can find some discussion about how to do it on this issue.
