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=4etc.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)
Does noindex metatag have a negative effect on the canonical URLs PageRank?
seo;google index;canonical url;noindex;rel canonical
You should not use both noindex and rel=canonical, because noindex won't let pages pass any PageRank to its canonical version.  rel=canonical is a hint, not a directive, so Google will decide which page to take and show in search results.Here are posts at seroundtable, there they cite John Mueller's comments, from Google:  No, you should not combine the noindex with a re-canonical pointing at  an indexable URL
