My site http://www.billysclaypots.com is shown in google without www. in front when I search for it by "billys clay pots". How can I make it so google shows up www. in front, I know usability studies confirm that users are less like to go to a URL without the www as they think there is a fault with the site.
I've already added a line to my .htaccess to redirect nonWWW requests to WWW and it works:
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
My only guess is that I may have submitted the site to google/addurl without the www in front ....
