I doubt that if i have backlinks from a noindex in Google SE but other SE may indexed that page. Does Google count those links as a backlink juice?
for google not to follow the link on a page, the following robot tag needs to be added <meta name="ROBOTS" content="NOINDEX,NOFOLLOW"> Code (markup): if it only shows noindex, then google will not index the page but will follow the links meaning link juice for you
