Indexability Checker

Four signals, and they have to agree: the meta robots tag, the X-Robots-Tag HTTP header, the canonical tag, and robots.txt. This tool reads all four for a URL and tells you the net result — plus, crucially, any conflicts between them (the “crawled, currently not indexed” trap).

It’s the most common silent indexing bug. If robots.txt blocks the URL, Google can’t crawl the page — so it never sees the noindex tag. The page can then stay in the index (often as a bare URL with no description). The fix is to allow crawling so the noindex is actually read, or rely on robots.txt alone without the noindex.

Your page’s canonical tag points to a different URL, telling Google “index that one instead of this.” That’s correct for duplicate or parameter URLs, but if it’s pointing somewhere unexpected, this URL won’t get indexed and its ranking signals flow to the canonical target. The tool flags it so you can confirm it’s intended.

It applies the same core rules Google uses: it finds the most specific user-agent group, matches your URL’s path against the Allow/Disallow rules with wildcard (*) and end-anchor ($) support, and lets the longest matching rule win (with Allow breaking ties). It’s a faithful approximation for the common cases.
