About canonical tags
- Canonical tags help prevent duplicate content issues
- They tell search engines which version of a page is the \"main\" one
- Use canonical tags when you have similar or duplicate content on multiple URLs
- The canonical URL should be the preferred version you want to rank in search results
Best practices
- Always use absolute URLs (including https://) in canonical tags
- Place the canonical tag in the <head> section of your HTML
- Each page should have only one canonical tag
- The canonical URL should return a 200 status code, not 404 or 301
- Use self-referencing canonical tags on unique pages
Verify canonical tags to avoid duplicate content SEO issues.
