Case Study: Auto Trader achieves 90% lower CPA and simplified campaign workflows with AppNexus

Auto Trader Simplifies Its Workflow and Optimizes Performance With The AppNexus Programmable Platform

Auto Trader, the UK and Ireland’s largest digital automotive marketplace, needed its small programmatic team to grow audience reach efficiently while staying within a tight digital marketing budget. Competing for the same customers made precise targeting essential, but manual campaign setup and optimization were taking too much time. Auto Trader turned to AppNexus and its Programmable Platform to improve targeting and reduce wasted spend.

With AppNexus’ Programmable Platform, Auto Trader used AI and machine learning to identify the best inventory, buy at the lowest rates, and automatically optimize campaigns toward the most valuable audiences. The results were strong: AppNexus helped reduce Auto Trader’s cost-per-acquisition by 90% over six months and saved traders three hours of manual work per campaign, giving the team more time to focus on strategy.
