During the quarter Criteo bought AdQuantic, a bidding technology company, in a talent-driven acquisition. And it agreed to buy Tedemis, a provider of real-time personalized email marketing.
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.
