canonical tag
 

The canonical tag is an essential tool in the search engine optimization toolbox. It is often a better solution that a 301 redirect in cleaning up duplicate content issues. A canonical link element is an HTML element that represent (rel="canonical").

I agree its better to use canonical tag instead of using 301 redirection to resolve duplicate content issue. But could you plz explain the way how to use or insert canonical tag in the duplicate pages??

its'a soft redirection likely(90-95%) to resolve the canonical issue.

if you have duplicate pages then for soft redirection we use canonical tag .... i think its temporary redirection...

Its a redirection tag if you have a duplicate site like with www or without www

Canonical tag is a redirection tag for site which consists of duplicate content of the site

The canonical tag is all regarding duplicate content and most popular content. it's a rather uncommon word, however etymologically speaking, it's applicable. it's derived from canon, that originally spoken biblical or profane rules and laws, a customary for judgement. Later it had been wont to talk over with the works of a author that had been accepted as authentic.
