Canonical tag
What is canonical tag?
A canonical tag tells search engines which URL is the preferred version of a page when several URLs show similar content.
Why it matters
Every indexable page should self-reference its canonical. Pointing canonicals at the homepage is a common, damaging mistake.
Canonicals are hints, not commands — conflicting signals such as internal links and sitemaps can override them.
