I always can roughly read an algo. This algo emphasises in my opinion inbound links from so called relevent sites. So in this algo in my opinion if your competitor has registered loads of domains with there keyword part of the the domain name and linked to target site they will win on this algo. So everyone out there go create a bull#*$! domain containing the keyword in url and link it to your main site if you wanna succeed on google on this algo. Of course I don't mean this as I consider it spam....... shame google don't.
