Getting started with user acquisition for apps: The complete guide

By Shani Rosenfelder·Nov 5, 2025·16 min read

Summary

The article emphasizes that despite market maturity, user acquisition (UA) is vital for app growth, with non-organic installs increasing year-over-year. Key challenges include high churn (only 5-7% of users make in-app purchases), rising media costs, mobile ad fraud (affecting nearly 1 in 4 installs), and fragmentation across devices and platforms. Attribution is central to solving these issues: using a single SDK from an unbiased provider allows marketers to track last-touch and multi-touch attribution, reducing double payments and optimizing spend.

The article outlines media categories (paid, earned, shared, owned) with prominent paid channels like Facebook, Google App Campaigns, Apple Search Ads, and Instagram. For budgeting, it recommends top-down or bottom-up approaches, emphasizing data-driven ROAS goals and A/B testing of creatives. Actionable takeaways include mapping in-app events to user value, creating lookalike audiences, and leveraging cohort analysis to identify high-LTV channels.

App Store Optimization (ASO) is also critical, focusing on keywords, visuals, and off-site factors like ratings and backlinks. Ad ops decision-makers should invest in fraud protection, diversify media partners, and continuously test and iterate campaigns to improve profitability.

Analyst Note

What's notable here is the explicit acknowledgment that the app economy's maturation has not slowed growth but intensified competition, making user acquisition a zero-sum game for many verticals. The article rightly positions attribution as the linchpin of profitable UA, yet the assumption that third-party attribution providers remain neutral arbiters is increasingly tenuous amid platform-driven measurement shifts (e.g., SKAdNetwork, GA4). For ad ops and UA teams, the fragmentation described—device types, OS ecosystems, and multi-touch journeys—isn't new, but the emphasis on fraud (1 in 4 installs fraudulent) signals that budget waste is now a board-level concern, especially as media costs escalate.

The analysis of PESO media categories is a useful framework, but the article glosses over the practical tension between owned/earned channels' lower cost and their scalability limits versus paid channels' immediate ROI. The key implication for monetization strategists: the interplay between UA cost and post-install behavior (churn, IAP rates) demands cohort-level ROI modeling, not just last-touch attribution. The mention of machine learning for fraud detection hints at an arms race where smaller teams are at a data disadvantage.

This piece reinforces that UA is no longer about volume but about surgical precision in targeting and measurement—a reality that requires integrated tech stacks and cross-functional buy-in.

How banks measure marketing ROI across every channel: Paid, owned, and app

Banks lack unified attribution for owned channels (email, SMS, push), web, QR codes, and re-engagement, causing budget misallocation. Omnichannel attribution connects all touchpoints to deposits and loans, revealing that owned channels can be 2-3X more cost-efficient than paid ads. Cross-device journeys (e.g., mobile ad to desktop conversion) remain invisible in single-device attribution. Banking-grade compliance (SOC 2, ISO 27001) is maintained. Ad ops decision-makers can optimize budget allocation by comparing true cost per deposit/loan across channels.

Marketing attribution: what it is and how to measure it

Marketing attribution is critical for connecting spend to revenue, but platform self-reporting and last-click bias distort budget decisions. Single-touch models (first/last-click) are simple but miss the full journey; multi-touch models (position-based, data-driven) are more accurate but require robust data. Mobile attribution is particularly challenging due to ATT, SKAdNetwork, and cross-platform gaps, necessitating a mobile measurement partner (MMP) for independent, deduplicated measurement. Clean attribution data is essential for AI-driven optimization—bad signals lead to bad decisions. Starting with position-based attribution and incrementality testing provides a practical foundation.
