Element Code: IN-016
Quick Reference (Critical Issue)
Issue: Canonical URL returns server error (500, 502, 503, etc.)
Impact: Canonicalization fails completely, may affect current page indexation
Fix: Fix server error or update canonical to working URL
Detection: Screaming Frog, Sitebulb, HTTP status checking
What Is This Issue?
A canonical pointing to a server error page is critically broken. Search engines cannot use this for canonicalization and may view it as a sign of site quality problems.
Why This Matters for Your Website
Server errors on canonical targets can cause both pages to have indexation issues and signal site reliability problems.
How to Fix This Issue
- Fix the error: Resolve the server issue on canonical URL
- Or update canonical: Point to a working URL
- Monitor: Set up alerts for 5XX errors
Tools for Detection
- Screaming Frog: Reports HTTP status of canonical targets
TL;DR (The Simple Version)
Your canonical points to a page with a server error. This is critical. Either fix the server error on that page or update the canonical to point to a working URL.
