comScore: Online health info category surges in past year

The online health information category has grown 21% during the past year, according to comScore. That's more than four times the growth rate of the total U.S. Internet population. WebMD Health leads the category with 17.3 million visitors in July (up 3% from a year ago). But comScore says three other health networks boosted the overall growth of the category: Everyday Health with 14.7 million visitors (up 63%), Revolution Health Network with 11.3 million visitors (up 182%), and AOL Health with 11.1 million visitors (up 88%). In June, nearly 54 million people had more than 1.5 billion display ad views via sites in the health information category. WebMD Health topped the list of display ad publishers, delivering 290 million display ad views and reaching nearly 15 million people at an average frequency of 19.3 times per visitor during the month.
