About Canonical Tags:
- A self-referencing canonical tag points back to its own URL to prevent accidental duplicate content.
- Cross-domain or cross-page canonicals consolidate ranking signals to a primary destination URL.
- Missing canonical tags leave duplicate URL versions (HTTP/HTTPS, trailing slashes, tracking parameters) vulnerable.
