A page has this URL:
http://example.com/pages/some-page/
There's a pagination on this page which uses a GET parameter page which would result in URLs like:
http://example.com/pages/some-page/?page=2
http://example.com/pages/some-page/?page=3
http://example.com/pages/some-page/?page=4
- etc.
All of these pages have the same canonical tag (without the page parameter):
<link rel="canonical" href="http://example.com/pages/some-page/">?
Still the URLs with parameter get indexed by search engines.
Would it affect the PageRank of the non-parameter version of the page to add noindex
to the URLs with the page parameter?
<meta name="robots" content="noindex, follow">
(as they all have the canonical URL of the page that should stay indexed)
