Questions people ask

What is a canonical tag?+

It is a hidden line telling Google which address is the main version of a page, so copies (with tracking codes, or http and https) do not compete with each other.

Should every page have one?+

Yes. A page pointing to itself is the safest setup and avoids duplicate content problems.

What happens if the canonical is wrong?+

Google may drop the page you care about and show a different address, or ignore the tag completely.
