Case Study: Mercedes achieves 71% lower CPA and more dealership foot traffic with The Trade Desk

Mercedes-Benz pays 71% less to drive foot traffic to dealerships

Mercedes-Benz worked with The Trade Desk and its agency team x to launch a new GLC SUV in Spain. The challenge was to raise brand awareness and reach luxury and EV car buyers in a complex market, using digital out-of-home advertising to target the right audiences in major cities.

Using The Trade Desk platform, the team activated first-party and third-party data targeting, AutoAllocator for budget optimization, and person-level cross-device attribution to measure dealership visits. The campaign delivered 70% of impressions to the target audience, improved CPA by 71% versus no-data impressions, and drove a 2.1x increase in dealership visits from the first week to the last, helping Mercedes-Benz generate incremental foot traffic.
