What is User acquisition?
User acquisition (UA) is the process of gaining new users or customers through marketing channels—paid ads, organic search, referrals, and content marketing. In mobile apps and SaaS, UA cost and efficiency are tracked through metrics like CPA, LTV, and payback period. Creative quality and testing cadence are key drivers of UA efficiency on paid channels.
How it relates to AI UGC
AI UGC helps reduce user acquisition costs by enabling high-volume creative testing. More ad variations mean faster discovery of winning creative, which lowers CPA and improves the ratio of lifetime value to acquisition cost.
Key statistics
- Average mobile app UA costs range from $1–5 (CPI) depending on category and platform.
- Brands that test 20+ ad creative variants per week typically achieve 30–50% lower CPA than those testing fewer than 5.
