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).
How Noindex Tag works
- 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 about Noindex Tag
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.

Robots.txt
robots.txt is a plain-text file at your domain root (yoursite.com/robots.txt) that tells crawlers which URLs they can and cannot request. It controls crawl budget, blocks staging paths, and points crawlers at your sitemap — but it does not prevent indexation.
Indexation
Indexation is the process of Google adding your page to its searchable index. A page must be crawled, deemed valuable, and pass duplicate-content checks before it's indexed. GSC's Coverage report shows every indexation state — indexed, discovered-not-indexed, crawled-not-indexed, and excluded.
Canonical URL
A canonical URL is the "master" version of a page you tell Google to index when the same or similar content is reachable from multiple URLs. Declared via <link rel="canonical" href="…" /> in the <head>, it consolidates ranking signals and prevents duplicate-content dilution.
Crawl Budget
Crawl budget is the number of URLs Googlebot will request on your site in a given period. It's a function of your site's host load capacity and Google's "crawl demand" (how important + fresh your content appears). Small sites rarely hit the limit; sites over ~10k URLs must manage it actively.
