Case Study: Add3 achieves 80% more efficient rental leads in cookieless environments with Quantcast

Add3 takes home 80% more efficient rental leads in cookieless environments

Add3, a Seattle-based digital agency specializing in omnichannel campaigns, needed to drive rental leads for a home-rental client as they expanded into new markets while preparing for a cookieless future. Their challenge was to seamlessly connect prospecting and retargeting without time-consuming manual ad balancing and to maintain performance in environments where third-party cookies are limited or absent.

Add3 used the Quantcast Platform and Ara™ AI to automate budget allocation, simplify ad set management, and deploy lookalike modeling to find net-new customers, while Quantcast’s cookieless solution enabled measurement and optimization in untapped environments. The approach delivered stronger audience insights (career/job-site visitors were 2x more likely to convert), a 50% increase in rental leads, and leads that were 80% more efficient (80% lower CPA) in cookieless environments.
