MediaPost expounds upon a Hitwise report that MySpace is Google's #1 traffic source:
GOOGLE, CURRENTLY REPORTED TO BE in talks with MySpace.com, receives the highest percentage of its traffic from the social networking site--accounting for 8.7 percent of the search giant's total traffic during the week ending May 6, according to data released Thursday by Hitwise.
The traffic numbers reveal the high stakes of the search partnership talks that Google and MySpace are engaged in, according to a report from the Financial Times. The same report also stated that competitor Microsoft was likewise engaged in talks, meaning that Microsoft's gain could be Google's loss.
According to Bill Tancer, Hitwise's general manager of research, the deal is a defensive one for Google. Similar to the AOL-Google deal last year, where the search giant bought a major stake in AOL amid rumors of a possible AOL-MSN deal, Google is engaged in an effort to protect one of its major traffic sources.
Don't cry for MSN, though. ComScore reports that they have the most popular blog service online. I think they'll be okay.
