Google showing pages with ?page=2 urls
Those links appear in Google's index because they're linked to on your site (presumably the pager generates those links for you) and you allow Google to crawl and index them.

If you do not want those pages to be crawled and indexed by Google, then you can disallow it by adding the following to the robots.txt for your site (btw.: this has little to do with Drupal):

Disallow:*?page=*


This will stop googlebot (and msnbot) from crawling the pages that is linked to with a link that contains this pattern.

Note that wildcards are not part of the Robot Exclusion Standards (but are supported by googlebot and msnbot), so don't expect any rule with wildcards to be widely recognised by robots.
