Miva won the business from incumbent Google, after a competitive pitch that also involved Yahoo! Search Marketing.
Miva will deliver six pay-per-click ads at the bottom of every page across all 12 sites in the Conde Nast network, including Vogue.com, GQ.com, Glamourmagazine.com and the newly launched Stylefinder.com.
The combined page impressions of all 12 sites is more than 54 million per month, according to the publisher. The deal also covers pay-per-click ads within 500,000 opt-in e-mails sent to subscribers.
