I recently saw that Google was leaving some of my pages listing with URL only while searching for "site:www.mysite.com".
Today I did a "site:mysite.com" and notice it lists both my pages with and without the www.
So, I think some site has linking to me without the "www" and this is causing this, but I'm not sure.
I've always verified I link my self and my internal links include the prefix.
So, two questions :
1.- How do I fix this?
2.- How do I prevent this in other sites?
