Has Groupon's ship sailed? Well, with its IPO pending, the group-buying leader has seen traffic decline nearly 50% since its peak in the second week of June.
That's according to new Hitwise data based on Web-based traffic, but excluding mobile and app-specific traffic.
"Regardless ... the drop-off in Groupon traffic this summer has been significant," according to Bill Tancer, GM of global research at Hitwise.
During the same time period, rival Living Social saw a 27% increase in visits to its site.
