Noindex is a robots meta tag directive (meta name="robots" content="noindex") that tells search engines not to include a specific page in their search index. The page can still be crawled, but it will not appear in search results.
Why Noindex matters for SEO
Accidentally noindexing important pages is one of the most common and damaging SEO mistakes, especially after site migrations when staging noindex tags are left on production pages. A single misplaced noindex tag can remove a high-traffic page from search results entirely.
Pro tip on Noindex
Audit all pages for unintentional noindex tags. Check that staging environments use noindex but production does not. Verify via Google Search Console's URL Inspection tool. Never combine noindex with a canonical tag (conflicting signals).
