# noindex

Reviewed on 2026-10-06.

## What it means

noindex is a directive that tells compatible search engines not to include a page in their results. It can appear in a robots meta tag in the [HTML](/en/resources/glossary/html-the-web-s-markup-language) or in the X-Robots-Tag HTTP header. Its effect depends on the [crawler](/en/resources/glossary/crawler) accessing the response and recognizing the instruction. The directive does not make the URL private or prevent people from opening the content.

## Why it matters for marketing

For marketing and [SEO](/en/resources/glossary/seo), it is useful when a public page should not appear in search, such as certain internal search results or versions with no discovery value. It is also a common cause of unintentional exclusion: test templates may retain the directive after publication. The review should check the actual pages, not just the [indexing](/en/resources/glossary/indexing) toggle in the CMS.

## Example in practice

A new landing page inherits noindex from its template. It opens normally and is in a [sitemap](/en/resources/glossary/sitemap), but the directive still instructs search engines to exclude it from search. In another scenario, the team adds noindex and also blocks the URL in [robots.txt](/en/resources/glossary/robots-txt). Google may be unable to access the page to read the new instruction, leaving a previous record in place for some time.

## How to apply or check it

Inspect the headers and HTML of affected URLs, including variants and redirects. Check the [crawling](/en/resources/glossary/crawling) rules and use [Search Console](/en/resources/glossary/google-search-console)'s URL Inspection tool to see what Google received. After correcting an accidental exclusion, monitor for a new crawl and indexing. Removing the directive does not guarantee immediate inclusion or a particular ranking.

## Important distinctions

noindex is not equivalent to [canonical](/en/resources/glossary/canonical), which indicates a preference among duplicate or very similar pages. It also does not replace authentication for confidential content. Avoid using the directive as an automatic solution to any editorial overlap: a useful page may need an intent review, content consolidation, or a redirect, depending on the issue and the data.
