Noindex: Keeping a Page Out of Search Results
Noindex is a directive that tells search engines not to show a page in results while it stays live on the web. Learn the meta tag and the HTTP header versions.
Noindex is a directive that tells search engines not to show a page in search results, while the page remains live and accessible on the web.
How Noindex Works
The most common form is a meta tag in the page head, and for non-HTML files like PDFs the same instruction travels in an HTTP header called X-Robots-Tag.
Either way, the page stays online for anyone with the link; noindex only changes whether search engines list it.
Noindex vs Nofollow
Noindex keeps a page out of the results. Nofollow stops a page from passing authority through its outbound links.
The two do different jobs, and combining them as "noindex, nofollow" is only necessary when a page should both stay hidden and pass no weight along.
When to Use Noindex
- On thin or low-value pages you still want to keep online.
- On staging, thank-you, and internal tool pages that add nothing to search.
- On duplicate archives or filters that do not deserve a result of their own.
Getting Started
- Add the tag or header only to pages you truly do not want listed.
- Audit for accidental noindex, since a copied template can hide an entire section.
- Remember noindex still lets the page be crawled, so keep canonicals and links tidy.
The site: a checkout flow leaves a thank-you page indexed, and it starts ranking for the brand name.
The reading: searchers land on a near-empty page that does not belong in the results.
The fix: the thank-you page gets a noindex tag, and the brand query returns the pages that matter.
Why it works: noindex cleans up the index without removing the page a customer still needs after ordering.
Quick Tip
When a page disappears from results unexpectedly, check the rendered HTML for a noindex tag that should not be there.
