ValueClick Launches Premium Health & Wellness Network

Targeting and potential reach of 20MM+ give edge to AdRx Media clients

Westlake Village, Calif. – SEPTEMBER 15, 2008 – ValueClick, Inc. (Nasdaq:VCLK) today announced it has launched AdRx Media, a premium health and wellness online advertising network with a potential reach of more than 20 million unique visitors per month, according to comScore Media Metrix.

AdRx Media is comprised of several well-known publishers, including Britannica Health, HealthGrades, Healthy.net, Merriam-Webster Medical Dictionary, OrganizedWisdom.com, Wrong Diagnosis and more than 50 other high quality health and wellness information sites.

AdRx Media gives advertisers a way to reach consumers while they are engaged in seeking health information on more targeted sites beyond the largest health properties. For instance, according to comScore Plan Metrix June 2008 data, WebMD Health reaches only one in seven people who have searched for health information related to an ailment online and Everyday Health reaches only one in eleven.

"AdRx Media is filling an important gap by giving advertisers an efficient way to reach a more engaged audience as they seek information on focused health sites other than general health properties," said James Kiernan, vice president, group director at MediaVest. "Having a reliable partner to aggregate inventory on content related to all major health conditions is a service I expect media buyers in the health category will be very receptive to."

AdRx Media offers advertisers a convenient way to reach consumers as they go online to learn more about any health related issue, with complete transparency into the sites where their ads will appear. The extensive reach of AdRx Media provides several ways to reach any health-conscious audience via contextual placements alongside condition-specific content and other demographic, psychographic and technographic targeting capabilities.

"The response to AdRx Media among marketers and agencies during our initial charter period has been overwhelmingly positive," said Denise Zaraya, director, AdRx Media. "They recognize the value of targeting niche content with a partner that can guarantee quality, transparency, expertise and scale."

The network is managed within the ValueClick Media division in the U.S. and utilizes its advanced network technology and expertise. A dedicated account management and media development team works with a unique set of AdRx Media publishers and advertisers under the direction of Ms. Zaraya.

AdRx Media is exhibiting and Ms. Zaraya will speak on a panel entitled "DTC Advertising and New Media" at the PharmaMed conference in New Brunswick, New Jersey September 15-16. On September 18-19, AdRx Media will exhibit at the OMMA Global conference in New York, where Ms. Zaraya will lead a workshop on "Strategies for Maximizing Performance with Vertical Networks."
