Using .htaccess to Redirect www and non-www

Its really important for new blogs or websites to deal correctly with canonical URL’s. If not then you will end up with bad SEO resulting in search engine ban. So we will see how to redirect www and non-www.

What are canonical URL’s?

Canonical urls are the search engine friendly urls. According to Google they call this process as Canonicalization which is the process of picking the best url when there are several choices, and it usually refers to home or index pages.

For example, in the view point of humans these urls are the same:

But technically all of these urls are different. Search engines treat all these urls as entirely different. A web server could return completely different content for all the urls above. When Google “canonicalizes” a url, it tries to pick the best url from that set.

The Problem?

Since search engines considers all the above urls as entirely different, the content will still remain the same in all the urls. This may lead to duplicate content issue.

Solution: Use Permanent www/non-www redirects

Choosing whether to redirect domain to completely www or without www(non-www) will avoid duplicate content. This also help to avoid the possibility of split page rank.
