URL canonicalization is used when two different URL contain the same content and duplicate content issue occur so at that time canonicalization is useful to tell search engine robots that this URL is using content of this URL.

I.e.: http://www.example.com/123.php and http://example.com/12345.php, suppose these two dynamically generate URLs have the same content but search engine count these two as a two different URLs so for search engine bots these two different URLs have the same content and duplicate content issue occur.

At this time you can use canonicalization by putting

<link rel="canonical" href="http://www.example.com/123.php"> in the head part of http://example.com/12345.php this page. It tells search engine robots that this page is using content of http://www.example.com/123.php or these two are the same page.

Canonicalization describes how a site can use slightly different URLs for the same page - for example: if http:/ /www. abc .com and http:// abc .com resolves to the same page. If this happens, search engines may be unsure as to which URL is the correct one to index.
For rectification this issue you can use canonicalization by putting

<link rel="canonical" href="http://www. abc. com/"> in the head part of main(index) page.
