Canonical points at an unusable URL
What this page tests
Check Canonical target health (indexability.canonical_target_invalid), alert indexability.canonical_target_invalid.
Monitored pages declare a canonical that errors, redirects, or is noindex. Google is likely to ignore the annotation and pick its own canonical instead.
Why it matters
Monitored pages declare a canonical that errors, redirects, or is noindex. Google is likely to ignore the annotation and pick its own canonical instead.
How the fail is produced
Canonical href points at /500, which returns a non-2xx status.
This page is part of the TechDash Test Site used to exercise the TechDash desktop app. Each fixture isolates a single check so you can add one path at a time and see a clear pass or fail. Search engines and users rely on stable HTTP responses, index signals, metadata, and site files. When those signals drift, organic visibility, crawl efficiency, and measurement can all suffer. Keep the homepage as the healthy control origin, then monitor the specific path you want to fail. Substantial body copy is included so thin-content and soft-404 heuristics do not fire unless that is the intended test.
