Have you ever wondered if there is a difference between using http://www.yoursite.com and http://yoursite.com for your site links? Does this affect your PageRank?

So can you use both www.yoursite.com and yoursite.com to link to your site? Yes you can, but I strongly recommend that you don’t!

Why? For SEO (Search Engines Optimization) reasons you should always use the same form for your links, pick one (with www or without www) and stick to it. This is called canonicalization and it means picking the best URL when you have a choice.

Because www.yoursite.com is not the same as yoursite.com and if you have different inbound links to both URLs, this could cause two problems:

First, some search engines might “think” that this is a duplicate content and penalize your site for this!

Second, splitting your links will affect your PageRank as PageRank is all about links, so if you have 1000 inbound links to www.yoursite.com and 500 inbound links to yoursite.com then you will have different PageRank for both URLs and you will lose valuable inbound links because they will be split into links for both URLs.

First, choose one form and stick to it. I prefer www.yoursite.com because this is what most people use. Also most people press (CTRL + Enter) in Internet Explorer or Firefox to append http://www and .com to whatever they have typed in the address bar of both major browsers.

Second, in Google’s Webmaster Tools, click “Preferred domain” and choose the same URL that you chose in the previous step.

Third, do something to redirect your traffic from one URL to the other (like from non-www to the www). That is what the major sites have done, try typing google.com, msn.com or yahoo.com and you will be redirected to www.google.com www.msn.com and www.yahoo.com The right method is to use “301 Moved Permanently” as this will make sure that search engines will combine the value of your inbound links.

I will show you two methods to do that. The best and the most frequently used method to do that is in a file called .htaccess (HTTP Access). It’s a text file used in most Linux based web servers. Just make a text file called .htaccess and upload it to the root directory of your site or append those lines to it if the file is already there:

NON-WWW TO WWW
Code:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^epicmoneymakers.com [NC]
RewriteRule ^(.*)$ http://www.epicmoneymakers.com/$1 [R=301,L]

This will redirect all the traffic from the non-www to the www of your site with the “301 Moved Permanently” server response.

In case you want to go from www to non-www.

WWW TO NON-WWW
Code:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.epicmoneymakers.com [NC]
RewriteRule ^(.*)$ http://epicmoneymakers.com/$1 [R=301,L]

Obviously with either of the codes above, you need to replace “epicmoneymakers.com” with your own URL.
