Canonical Is Malformed or Empty

No Comments

Quick Reference

Element Code: IN-010

Issue: Canonical tag exists but contains invalid or empty URL

Impact: Canonicalization fails, potential duplicate content issues

Fix: Add valid absolute URL to canonical tag

Detection: Screaming Frog, Sitebulb, HTML inspection

What Is This Issue?

A canonical tag with an empty href or malformed URL provides no guidance to search engines. This is worse than having no canonical at all because it suggests technical problems.

Why This Matters for Your Website

Empty or invalid canonicals waste the opportunity to control indexation and may signal quality issues to search engines.

How to Fix This Issue

  1. Identify malformed tags: Crawl site for canonical issues
  2. Fix URL format: Use absolute URLs with protocol
  3. Remove if empty: Empty canonical is worse than none

Tools for Detection

  • Screaming Frog: Reports malformed canonicals

TL;DR (The Simple Version)

Your canonical tag is empty or broken. Either fix it with a proper absolute URL or remove it entirely. An empty canonical is worse than no canonical.
