What is noindex and how to use it correctly?

Short answer

Noindex is a meta tag <meta name="robots" content="noindex"> in page code telling search engines: 'don't add this page to the index'. Unlike robots.txt (blocks crawling), noindex allows crawling but blocks indexing. Used for thank-you pages, cart, account, filter duplicates, thin tag pages. Often combined with follow/nofollow for link equity control.
