Frequently Asked Questions
Can this inspect a live page?
No. Copy the page markup and paste it into the tool.
Does a canonical tag redirect visitors?
No. It is a hint for search engines about the preferred version of a page; it does not redirect the browser.
Should a canonical URL be absolute?
An absolute URL is generally preferred so the canonical clearly identifies the complete preferred address.
Will search engines always follow the canonical tag?
No. Search engines treat it as a signal and may select a different canonical if other evidence points elsewhere.
