Clients who turn on mobile are spending significantly more with Criteo than those with only desktop activated, according to Rudelle. For some of them, traffic sourced to mobile provides 25% of sales they earn through the Criteo platform.
Mobile contributed to 15% of Criteo's revenue after traffic acquisition costs in March, compared with 10% in December and 2.5% in September. It has solutions for both browser and in-app ad delivery, and can offer so-called "deep linking" in apps. The click-through rate in mobile is as strong or stronger than desktop placements, while the probably more important "first-click conversion rate" that proves the clicks are intentional and not a result of "fat finger syndrome" are on parity with desktop.
"People in mobile are really engaged," said Rudelle.
