Noindex Tag — Definition & Meaning
What is Noindex Tag?
A noindex meta tag or X-Robots-Tag HTTP header tells search engines to crawl a page but exclude it from their index. It's the correct way to remove pages from Google — unlike robots.txt (which blocks crawling but not indexation of already-known URLs).
Key points
- HTML: <meta name="robots" content="noindex, follow" /> in the <head>.
- HTTP: X-Robots-Tag: noindex header — works on non-HTML files (PDFs, images) that can't hold meta tags.
- "noindex, follow" keeps link equity flowing through the page; "noindex, nofollow" isolates it — use follow unless you have a specific reason.
- For fast removal: request removal in GSC → Removals AFTER adding the noindex tag, not instead.
- Do NOT block a noindex'd page in robots.txt — Google can't see the noindex tag on a page it can't crawl.
Example
Thank-you pages, internal search results, tag archives, and staging URLs should all noindex. Product pages, blog posts, and landing pages should never noindex.
Frequently asked questions
What is the difference between noindex and disallow?
Noindex = "you may crawl but don't include in results". Disallow (robots.txt) = "don't crawl at all". Use noindex to remove pages from results; use disallow to save crawl budget on unimportant URLs.
How long does it take for a noindex page to disappear from Google?
Usually 1-4 weeks — Google needs to recrawl the page to see the tag. Speed it up by requesting recrawl in GSC → URL Inspection → "Request indexing".
Can I temporarily noindex a page?
Yes — add the tag, wait for recrawl and removal, then remove the tag when you want the page back. GSC → Removals also offers a 6-month temporary block for urgent cases.
