I know that nofollow prevents link juice from being passed across a link.  But if search engine robots discover a link with a nofollow on it, will they add that link to their crawl queue?In other words, if I create a link to a brand new page and put a rel=nofollow attribute on that link, will it prevent search engine bots (particularly Googlebot) from crawling the page.  (Assuming that this link remains the only link into that page.)I've read conflicting reports about this over the years and I'm looking for authoritative references about the current state of affairs.  Official statements from Google or published results of independent testing would be ideal.
Does a nofollow attribute on a link prevent URL discovery by search engines?
web crawlers;nofollow
This article from 2006 explains an experiment where a new page was created an linked to only with nofollow.It finds that Google:Follows the link (crawls the URL with Googlebot)Does not index the content of the pageThe article also publishes results for MSN and Yahoo.In 2009 Google significantly changed the way that nofollow works.  Results regarding nofollow from before before the change would be good to re-test.   A 2012 experiment on the discovery of a URL from a nofollow link found that the page does not get indexed (although it does not report on whether or not it got crawled.)
