What does Google say about SEO? /

Official statement

A no-index tag on a page does not stop Googlebot from crawling the page; it only prevents its indexing. On the other hand, blocking via robots.txt truly prevents crawling. If you see Googlebot crawling a URL blocked by robots.txt, they are probably false Googlebots.

TL;DR

The no-index tag prevents indexing but not crawling. To block crawling, use the robots.txt file. Be cautious of false Googlebots if you notice crawling despite a block.
