Frequently Asked Questions
A noindex meta tag or header explicitly tells search engines not to include the page in search results (while still allowing them to crawl and see the tag); robots.txt instead asks crawlers not to even fetch the page at all - different mechanisms with different practical effects.
Yes, exactly what a noindex tag accomplishes - the page can be fully crawled and its noindex directive read, while still being deliberately excluded from appearing in search results.
A very common cause is a noindex tag left in place after migrating a staging/development site to production, where it was originally added intentionally to prevent an unfinished site from being indexed.
They have related but distinct effects - a canonical tag consolidates ranking signals toward a different preferred URL, while noindex is a more direct, explicit instruction not to index this specific page at all, regardless of any other page.
Checking directly with a tool like this one is the fastest way; search engine webmaster tools/consoles also typically report indexing status and reasons a specific page may have been excluded.
