Zynga Announces 100 Million Monthly Unique Visitors

Last week we wrote about Zynga surpassing the 200 million monthly active users milestone, but how many of those users are unique? Today the company is sharing that they have over 100 million unique users each month. While Zynga also has games on the iPhone, it would be safe to say that almost one-third of Facebook users are playing Zynga games each month. 66 million users have played Farmville in the past month, making up a significant portion of Zynga’s traffic.
