Two Demand Media properties—Livestrong.com and eHow Health—are quickly moving up the list of most visited health sites online, according to comScore data.  

In September, Livestrong.com and eHow Health came in at 13 and 15, respectively, on comScore’s monthly top 20 consumer health sites, as measured by unique visitor count. Livestrong.com was built through a partnership with the Lance Armstrong Foundation, and features nutrition, health and lifestyle content. eHow Health offers consumers step-by-step instructions on healthy living. Richard Rosenblatt co-founded the company in 2006 with Shawn Colo.
