For the first time, PBSKids.org is the top-ranked children’s site for number of videos viewed, according to comScore Video Metrix (September 2010). Viewers spent an average of 47 minutes watching nearly 88 million free educational videos in September, PBS said in a statement today (Nov. 1). That’s twice the monthly average for other top children’s sites. The PBS Kids preschool and PBS Kids Go! players offer free access to more than 3,800 streaming full-length episodes and video clips. PBSKids.org attracts an average of 9.5 million unique visitors per month, with a 72 percent repeat visitor rate. Traffic has increased 28 percent over last September, according to Google Analytics.
