Ghost NoIndex Detector - HTTP Header Checker

About

Ghost NoIndex Detector catches the hidden X-Robots-Tag noindex HTTP headers that most SEO tools completely miss. While standard audit tools only check the HTML meta robots tag, websites can block search engine indexing through invisible HTTP response headers — and you would never know by looking at the page source.

This extension monitors HTTP response headers in real-time and instantly alerts you.

Features:

Automatic icon alert — turns red with a warning badge the moment a noindex HTTP header is detected
Detects X-Robots-Tag directives including noindex, nofollow, none, noarchive, and nosnippet
Checks both HTTP headers AND HTML meta robots tags in one view
Ghost NoIndex detection — flags pages blocked only via HTTP headers with no visible HTML tag
Googlebot-specific meta tag detection
Combined indexing assessment with clear pass or fail checklist
Full HTTP status code reporting
Key SEO-relevant response headers displayed
Canonical URL detection
Real-time monitoring with no manual scanning needed

The problem this solves: A developer or server admin can add X-Robots-Tag noindex to HTTP response headers, which silently blocks a page from Google. This is invisible in the HTML source code, invisible in most SEO crawlers, and nearly impossible to catch without inspecting raw HTTP headers. Ghost NoIndex Detector watches for this automatically on every page you visit.
