URL Question - www or not?
Let's say my web site is www .sitename. com. Within Wordpress, I have the option to display the Wordpress Address (URL). I've currently got that set to http :// sitename. com. (spaces added so the post doesn't create a hyperlink).
Within Google Webmaster tools I have the option of setting either www .sitename. com or site name.com as my preferred domain. Currently neither of these options are ticked.
I understand that I can access my site by typing the full URL - http: //www .sitename.com, the www version (without the http), or the site name.com.
I need some help understanding the implications of the URL structure. Is there a benefit in sticking with one? If there is, what settings do I need to change in WP or anywhere else so Google knows what to index. I understand that having different versions could lead to a dilution of PR. Is this correct? Also, how should I structure my backlinks? Up to now, most of my backlinks from EZA etc have pointed to http ://www .sitename .com. Is this ok, or do I need to change something?
Thanks in advance for your help.
