What is Canonical URL Tag Generator?
A canonical tag tells search engines which URL is the preferred version of a page. It is helpful when the same content can appear with and without a trailing slash, through index.html, through tracking parameters, or through alternate paths. Static sites often need canonical tags because routing and deployment output can create multiple versions of the same page.
quickAnswer
Use the canonical URL tag to tell search engines which version of a page is the authoritative one when duplicate or near-duplicate content exists across multiple URLs.

limitations
- A canonical tag is a hint, not a directive. Google may choose a different URL as canonical.
- Canonical tags on pages with fundamentally different content are ignored by search engines.
- Self-referencing canonicals are recommended. Every page should link to itself as canonical unless there is a specific consolidation reason.
