• Purpose: Tell search engines which version of a page is the "main" one

• Duplicate Content: Prevents SEO penalties from similar/identical content

• When to Use: Multiple URLs for same content, query parameters, mobile versions

• Self-Referencing: It's OK (even recommended) to use on the canonical page itself

• Absolute URLs: Always use full URLs with protocol (https://)

• Not a Directive: Search engines may ignore it if they think another URL is better

• Place in <head> section of HTML
