Technical SEO
Canonical
Also known as: rel canonical · canonical URL
An indication of the preferred URL for identical or very similar content.
A practical example
A parameterized URL points to the main product page.
What should I know?
It is a signal; the search engine may choose another representative URL.
Technical SEO in practice
Check crawler access, server responses, and content processing separately. Then assess indexing and search appearance. These stages are connected but distinct and need different diagnostic methods.
