How do I fix the canonical-integrity audit test in WebCare Pro Auditor?

Add a self-referencing in the of every indexable page. Ensure the canonical URL is absolute (includes https:// and full domain path), not relative. Enforce consistent trailing slashes across your routing system to match the declared canonical. Ensure the canonical link returns a 200 OK status and is not redirected or blocked by robots.txt.
