I recently learned about canonicalization, and I don't really understand it that much, I just know it has to do something with how there are differnet names for the same website, for example, www.domain.com and domain.com. I know it's better for all internal links to link to the same place, as in, internal links should go, say, to www.domain.com/, instead of domain.com and www.domain.com. It's good for SEO and eliminates all possibilites of duplicate content. Somebody could probably explain it better than me.

basically, canonicalization is the process of finding your domain.

Actually.......

In information technology, canonicalization (pronounced KA-nahn-nihk-uhl-ih-ZAY-shun and sometimes spelled canonicalisation) is the process of making something canonical -- that is, in conformance with some specification. To canonicalize (as well as the slightly less tortured variant canonify) is to ensure that data conforms to canonical rules, and is in an approved format. Canonicalization may sometimes mean generating canonical data from noncanonical data.

Canonicalization is used for a variety of computer and Internet-related applications. In a sendmail context, canonification (or canonicalization) describes the process used to complete Mail-From addresses where necessary on incoming messages. When the canonify feature is turned on, a defined default domain name is added to the user name on an incoming message, so that username is translated to username@domain. Within the Extensible Markup Language (XML), canonicalization ensures that an XML document adheres to the specified format.

Does it have significant effects on SEO? If it's not that important, I don't want to spend a lot of time on it.

Yes, check your pagerank for www.domain and domain.com, they could (and often are) different.


You can add this to your .htaccess file to make all visits to domain.com go to www.domain.com:
RewriteCond %{HTTP_HOST} ^domainname.(.*) 

RewriteRule ^(.*)$ http://www.domainname.com/$1 [R,L] 

You can also specify this for Google at http://www.google.com/webmasters

I put the code into my site and it didn't redirect. Somebody gave me a code awhile back that did it but when I added another site to my hosting it messed it up so I had to take it down.
