Digiday: Conde Nast U.K., with 10 titles including Vogue, GQ and Wired, has rebuilt its digital backbone to capitalize on the explosion in mobile and native advertising. Eight months in the making, the work is aimed at helping the publisher roll out digital products faster and run more native advertising. Like many publishers, Conde Nast has seen desktop homepage traffic decline to 4 percent of its overall audience while mobile traffic has grown to represent about half its traffic.
