No canonical URL declared

The canonical tag tells Google which URL to consolidate ranking signals to when duplicates exist.

Why it matters

Without canonical, Google guesses — and may pick HTTP over HTTPS, or a URL with tracking params.

Example fix

<link rel="canonical" href="https://example.com/page" />
