Canonical Tag ???
 

Hi !!
What is Canonical Tag, and Advantages/Disadvantages of this tag?

A canonical link element is an HTML element that helps webmasters prevent duplicate content issues by specifying the canonical or preferred version of a web page as part of search engine optimization.

A rel canonical tag is a special tag that is inserted into the header of your HTML that helps communicate to search engine bots the relationship of that piece of content to others on your site. Canonical tags tell the search engine bots which pieces of content are the original or primary ones and which are duplicates. This way the bot will pass over the duplicates and only index and give link credit to the primary piece.

Canonicalization can be a challenging concept to understand , but it's essential to creating an optimized website. The fundamental problems that canonicalization can fix stem from multiple uses for a single piece of writing–a paragraph or, more often, an entire page of content–that appears in multiple locations on one website or on multiple websites
