Canonical tag checker FAQ
Make the preferred URL explicit.
Should every indexable page have a self-referencing canonical?
A self-referencing canonical is a common way to state the preferred URL explicitly, especially when parameters or alternate paths can expose the same content.
Can a canonical point to a different domain?
Yes, cross-domain canonicals are supported by search engines, but they should be intentional and the target page should represent the preferred version of the content.
Where does the canonical link tag belong?
Place the link element in the document head and use an absolute preferred URL that returns the intended indexable page.
