Bulk Indexability Checker — Free Page Indexability Tool
A page can exist on your site and still be completely invisible in Google and Bing — blocked by any one of five indexability signals. Paste up to 50 URLs to find out exactly which pages are blocked and why.
Checks five signals at once: HTTP status, robots.txt, meta robots, X-Robots-Tag, and canonical — plus automatic conflict detection.
What This Tool Checks — 5 Indexability Signals
Every signal is evaluated in sequence. A page can pass four checks and fail the fifth — which is exactly why a unified tool is more useful than running three separate checkers.
- HTTP Status Code
- The server must return a 2xx response. A 4xx (404 Not Found, 403 Forbidden) or 5xx (500 Server Error) means the page cannot be crawled regardless of any other directive. A 301 redirect is followed — the tool reports the final destination's status.
- robots.txt
- The robots.txt file is fetched once per domain and parsed separately for Googlebot and Bingbot tokens. A Disallow rule blocks the crawler at the network level before it reads any HTML — so a noindex tag on a robots.txt-blocked page is effectively invisible.
- <meta name="robots"> / <meta name="googlebot">
- The HTML <head> is parsed for both the general robots meta tag and engine-specific variants (googlebot, bingbot). A noindex or none directive in either tag prevents the page from being indexed. Engine-specific tags override the general tag for that engine.
- X-Robots-Tag HTTP header
- This HTTP response header is checked before the HTML body and takes precedence over the meta tag. A server can return X-Robots-Tag: noindex on every response regardless of what the HTML contains — easy to miss, very common in CDN or CMS misconfiguration.
- rel=canonical
- The canonical link is detected from both the HTML <head> and the HTTP Link header. A self-canonical (canonical = current URL) is ideal. A cross-page canonical signals to search engines that this URL is a duplicate and the canonical target should be indexed instead.
Conflict Detection — The Hidden Indexability Problems
These scenarios are invisible when tools check signals separately. SERP.tools flags them automatically.
robots.txt blocks + noindex tag present
The crawler cannot read the noindex tag because robots.txt blocks access. The page may still appear in Google as a URL-only result (no snippet) because Google knows the URL exists from links — the exact opposite of what was intended.
noindex + cross-page canonical
Conflicting instructions: noindex says 'remove me', canonical says 'I belong to that other page'. In rare cases Google may transfer the noindex signal to the canonical target, penalising the page you actually want indexed.
X-Robots-Tag noindex overrides meta robots index
The HTTP header is evaluated before the HTML body. If the header says noindex but the meta tag says index, the page is effectively noindexed — a common result of CDN or reverse-proxy misconfiguration.

Frequently Asked Questions
Indexable means Google or Bing is allowed to show this page in search results. If a page isn't indexable, it receives zero organic traffic — no matter how good the content is.
A page is marked ✅ Indexable when nothing is blocking it: the server responds normally, your robots.txt doesn't tell the bot to stay away, and there's no 'noindex' instruction in the page headers or HTML. If any single blocker is present, the page is marked ❌ Not Indexable and the tool shows exactly which signal caused it.
Most likely one of the other four signals is failing. Common causes in order of frequency:
- HTTP status is not 2xx — a 4xx or 5xx response means the page cannot be crawled at all.
- robots.txt blocks the crawler — Googlebot or Bingbot is disallowed before it even reads the HTML.
- X-Robots-Tag header contains noindex — the HTTP header takes precedence over the HTML meta tag.
- The page redirects to a noindexed destination — the redirect chain ends at a blocked page.
A conflict occurs when two signals contradict each other in a way that produces an unexpected result. The most dangerous is robots.txt blocking + noindex tag present: the crawler is blocked by robots.txt and therefore cannot read the noindex tag in the HTML. The page may still appear in Google's index as a URL-only result (no snippet) because Google knows the URL exists from links — the exact opposite of what the noindex was intended to achieve.
Another common conflict is X-Robots-Tag noindex overriding meta robots index: the HTTP header is checked before the HTML, so even if the HTML tag says index, the header wins.
Googlebot and bingbot are different user-agent tokens and may be covered by different rules in robots.txt. Similarly, pages can serve a <meta name="bingbot" content="noindex"> tag to block only Bing, or an X-Robots-Tag: bingbot: noindex header. Bing covers Yahoo Search and Microsoft Copilot — so a Bingbot block is broader than it appears.rel=canonical points to a different URL. This tells search engines "this URL is a duplicate — please index the canonical target instead." The page itself is unlikely to appear in search results, even if it passes all other signals. The tool flags this as a warning but does not automatically mark the page as non-indexable, because canonical hints are not strictly enforced — Google and Bing may choose to override them.
