What’s surprising it how far behind Facebook is – with just 12.57 percent of visits. People are returning to the sites. In December 2007, 95% percent of traffic to the site are return visits, not first timers. Facebook also has loyal users because 93% of traffic was also returning visitors.
Another measure of stickiness is how much time people spend on the site. In December 2007, the average time spent on Bebo averaged a full 30 minutes and 24 seconds. That is a long, long time online.
Also note: while this is just for the US, Facebook is growing even quicker in the UK. Facebook has been growing and has increased its market share 10-fold over the past year.
