What is a canonical URL and why does it matter for SEO?

Canonical URL tells Google your preferred page version amid duplicates, preventing split signals that dilute rankings.

How do I check if my site has canonical issues?

Use Google Search Console's Coverage report or free tools like Hummus on Rails audit for quick scans.

Does www vs non-www really affect Google rankings?

Yes — Google treats them as separate sites without canonicals or redirects, halving your authority.
