Enter a URL to check robots index directives:

How the X-Robots-Tag Checker Works

This checker fetches the URL and inspects the two places search engines use for index directives.

  1. HTTP header check, the API reads the X-Robots-Tag response header, including rules that affect non-HTML files.
  2. HTML robots check, the tool extracts meta robots and googlebot directives from the page head.
  3. Directive parsing, values such as noindex, nofollow, none, noarchive, nosnippet, and max-snippet are normalized.
  4. Effective verdict, the result combines header and meta signals to show whether the URL appears indexable.

Why Robots Directives Matter

A single noindex directive can remove a revenue page from search, even if the page content, schema, and backlinks are strong.

  • Launch protection, staging noindex rules sometimes ship to production by accident.
  • Header visibility, X-Robots-Tag is invisible in page source, so many basic SEO tools miss it.
  • AI search readiness, GEO visibility depends on pages being crawlable, indexable, and machine-readable.
  • Cleaner audits, this tool complements the Meta Tag Checker by focusing only on index directives and HTTP headers.

Robots Directive Reference

X-Robots-Tag Checker: FAQ

What is an X-Robots-Tag header?
An X-Robots-Tag is an HTTP response header that gives search engines indexing instructions. It can apply to HTML pages, PDFs, images, and other files where a meta robots tag is not available.
How is X-Robots-Tag different from meta robots?
Meta robots directives live in the HTML head. X-Robots-Tag directives live in the HTTP header. Search engines read both, and a blocking directive in either location can affect indexing.
What does noindex mean?
Noindex tells compliant search engines not to show the URL in search results. If a page should rank organically, noindex is usually a critical issue.
What does nofollow mean?
Nofollow tells search engines not to follow links on the page for discovery or ranking signals. It does not necessarily remove the page from the index unless noindex is also present.
What does none mean in robots directives?
The none directive is shorthand for noindex and nofollow. It is a strong block for organic search visibility.
Can X-Robots-Tag block a page even if meta robots allows indexing?
Yes. If the HTTP header sends noindex, the page can be blocked even when the HTML meta robots tag is missing or set to index.
Should every page have a robots meta tag?
No. If a page should be indexed and followed, leaving robots meta absent is normal because search engines default to index and follow.
Does this checker store URLs?
No. The tool fetches the URL, reads robots directives, returns the result, and does not store page content or personal data.
