The article argues that artificial intelligence transforms user acquisition (UA) and targeting in the mobile gaming sector, where competition and rapid market shifts demand more precise, data‑driven approaches. It outlines the UA lifecycle—awareness, attraction, conversion, engagement, and retention—and explains how traditional manual tactics such as social media campaigns, influencer partnerships, and basic demographic targeting often lead to high costs and low retention due to limited precision. AI platforms, exemplified by Gamelight, address these shortcomings by continuously analysing granular user data to create detailed profiles and deliver personalised marketing messages in real time. Key benefits highlighted include enhanced engagement and retention, data‑driven decision making, scalability to evolving trends, cost‑effective ad spend through precision targeting, and the ability to adapt campaigns automatically. The article recommends a structured implementation: set clear objectives, select scalable AI tools, leverage comprehensive user data, monitor performance continuously, and remain adaptable to new insights. Gamelight’s case demonstrates rapid improvements in engagement metrics and sustained performance, illustrating AI’s capacity to optimise UA at scale. Overall, the piece concludes that AI‑enabled UA and targeting will become essential for developers seeking to attract high‑value users, maximise ROI, and maintain competitive advantage in the dynamic mobile gaming market.
