canonical problems

What is canonical problems is SEO?

 

Canonicalization is the process of picking the best url when there are several choices, and it usually refers to home pages. For example, most people would consider these the same urls:

* www.example.com
* example.com/
* www.example.com/index.html
* example.com/home.asp

But technically all of these urls are different. A web server could return completely different content for all the urls above. When Google “canonicalizes” a url, we try to pick the url that seems like the best representative from that set.
you can further read it from that url:

In other word, it's a way to avoid penalty from duplicate contents on a website.
