Interesant, am facut si eu un test si mi-a atras atentia un anumit sfat

You should set up a permanent redirect (technically called a "301 redirect") between these sites. Once you do that, you will get full search engine credit for your work on these sites. For example, www . gsmpedia.ro seems to have 5,808 inbound links whereas gsmpedia.ro has 5,762 inbound links. By correctly configuring a permanent 301 redirect, the search rankings might improve as all inbound links are correctly counted for the website.
Mi se pare ciudat, si sunt putin confuz.

Daca ma uit in Google Webmuster tools vad ca am posibilitatea sa setez "preferred domain". Momentan este default "Don't set an association."

Cum ar fi mai bine sa fac.. sa urmez sfatul celor de la WebsiteGrader si sa fac redirectul, sa modific "prefered domain" din webmaster tools sau sa merg in continuare asha.. pt. ca nu are nici o importanta, sau nu are o importanta majora.
