    Summary

    Summary

    A leading platform in the microdramas space faced rising acquisition costs and sought to expand its user base beyond mobile channels. By implementing a phased connected TV (CTV) strategy powered by audience signals, the platform achieved a 400% growth in user acquisition over six months while maintaining a stable cost per acquisition (CPA).

    Background

    The customer is a prominent player in the entertainment industry, specializing in microdramas—short, vertically filmed episodes designed for mobile consumption. Before deploying the CTV strategy, the company relied heavily on social and mobile channels for user acquisition, which limited its ability to reach new audiences and acquire high-value users.

    Challenge

    The primary challenge was to diversify the acquisition strategy to attract users with strong retention and monetization potential. Rising costs in traditional acquisition channels made it difficult to scale efficiently, prompting the need for a more effective approach to reach higher-value users.

    Solution

    The company, in collaboration with its agency MadHouse, launched a phased test-and-scale CTV strategy using The Trade Desk platform. The campaign began with an always-on CTV initiative in the U.S. to establish reach and performance benchmarks. As the campaign progressed, the team refined their targeting based on audience and content signals, structuring ad groups by demographics and viewer motivations. They created theme-based campaigns and utilized Kokai’s AI-driven capabilities to optimize audience targeting and improve performance.

    Results

    The campaign resulted in significant outcomes, including:

    • A 400% growth in user acquisition over six months while maintaining a stable CPA.
    • A first-day return on ad spend (D0 ROAS) that exceeded targets by more than 50%, with peak performance reaching 3-4 times the target levels.
    • An 87% improvement against cost per install (CPI) targets. Additionally, localized creatives with English subtitles outperformed dubbed versions, yielding a 59% higher ROI and nearly three times the install rate of benchmark creatives.

    Key Insights

    The deployment demonstrated that expanding beyond traditional mobile acquisition channels can unlock new audiences without sacrificing efficiency. Aligning audience strategy with content affinity and utilizing AI for audience optimization can enhance both acquisition efficiency and business results. This approach also established a framework for global expansion, allowing the platform to scale into new markets effectively.
