SEO edge-case controls
Use these parameterised toggles to simulate duplicate canonicals, a canonical pointing to a non-200 page, missing H1s and invalid JSON-LD.
Duplicate canonical
Adds a second canonical tag pointing at /services/.
Canonical to 404
Points the canonical at a missing URL to test non-200 detection.
Hide the H1
Removes the visible H1 to simulate heading-structure regressions.
Invalid JSON-LD
Injects malformed structured data so parsers can flag it.
