Could someone explain why my website appears in the SERPs without "www" :
For example, I search for keyworf "livre photo" on Live Search, my website is in position 6 :
Livre Photo : Le spécialiste de la création de livre photo imprimé et relié comme un livre à partir de vos photos numériques. Mariage, anniversaire, naissance, vacances ...
How come I do not have the www.livre-photo.com ?
Does it have an impact on ranking ?
I have modifyed htaccess to rewrite http://livre-photo.com into http://www.livre-photo.com so I would asume any robot should only see the "www" alias ?
