Canonical URLs: Prevent Duplicate Content Issues
A canonical link tells search engines which URL is the official version of a page, preventing duplicate content penalties.
Why This Matters
Without canonicals, search engines may split ranking signals across duplicate URLs (www vs non-www, HTTP vs HTTPS, trailing slash variants).
How to Fix
Add <link rel="canonical" href="https://yourdomain.com/page"> to every page.
