WHAT IS A CANONICAL URL?
Understanding Canonical URLs
A canonical URL tells search engines which version of a page is the "master" copy. This prevents duplicate content issues when the same page is accessible via multiple URLs.
Common Mistakes
Mixing http:// and https:// versions
Having both www.example.com and example.com
Inconsistent trailing slashes (/page vs /page/)
Including URL parameters in canonical (e.g. ?utm_source=...)
Using relative URLs instead of absolute URLs
Self-referencing canonical pointing to a redirect
Setting canonical on paginated pages incorrectly
Best Practices
Always use absolute URLs (https://example.com/page)
Be consistent with trailing slashes across your site
Choose one version (www or non-www) and redirect the other
