“The difference between a domain that’s six months old verses one year old is really not that big at all.”.
"Valuable (legitimate) domains are often paid for several years in advance, while doorway (illegitimate) domains rarely are used for more than a year. Therefore, the date when a domain expires in the future can be used as a factor in predicting the legitimacy of a domain".
“...When I checked the whois on them, they all had “whois privacy protection service” on them.

"The page layout on highest quality pages makes the Main Content immediately visible"
"In general, we don't follow them."
"First, anchors often provide more accurate descriptions of web pages than the pages themselves."
