Challenge

As part of their new omnichannel strategy to expand and diversify their ad mix, Auto Trader set out to launch a CTV campaign designed to drive incremental reach beyond their linear TV campaigns.

Solution

Partnering with GrowthAds, Auto Trader launched a broad-reach CTV campaign that mirrored their linear TV buy, enabling them to track incremental reach through Audience Project.

Results

Auto Trader’s CTV campaign successfully reached digital-only viewers who were not accessible through linear TV. The campaign delivered a 51% increase in incremental reach, representing 0.9% of the UK population. Key insights showed that 18-34-year-olds were the largest digital-only group, with 74-77% of them only reachable via CTV. In addition to driving incremental reach, the campaign generated significant site traffic at a very low cost per site visit (CPSV).
