User acquisition

Also known as: UA, UA marketing, app user acquisition

User acquisition, usually shortened to UA, is the practice of attracting new users to an app or product through paid media, organic channels and partnerships. It covers campaign planning, creative production, bidding, measurement and post-install analysis. The goal is a sustainable cost per user relative to the value those users generate.

What it is

UA teams run paid campaigns on networks such as app campaign platforms, search ad products and social and video channels, alongside organic work like store optimisation, content, referrals and PR. The discipline spans creative testing, audience and geography selection, bid and budget management, and the measurement setup that links spend to outcomes. It sits between marketing and finance, because decisions depend on what a user is worth over time.

Why it matters

Acquisition cost is one of the few levers that directly determines whether a product can grow profitably, so small changes in cost per install or conversion rate compound quickly. UA also shapes product data, because the audiences you buy determine the retention and monetisation you observe. Weak measurement leads to overspending on channels that only capture demand created elsewhere.

How it works

Practitioners set a target cost per acquisition derived from expected lifetime value and payback period, then test creative and audiences against it. Measurement relies on mobile measurement partners, Google Play Install Referrer on Android and privacy-preserving attribution frameworks on iOS, supported by incrementality tests or geo holdouts where attribution is thin. Reporting usually moves from install volume towards downstream events such as registration, first purchase or subscription start.

When it applies

UA applies once a product has a working activation and retention loop and the unit economics are understood well enough to set a spending limit. It is most intense around launches, new market entry and seasonal peaks, and it should pause or rebalance when retention or payback metrics deteriorate.

Examples

  • A subscription app sets a target of recovering acquisition cost within 90 days, then cuts channels that miss the payback window after two full cohorts.
  • A games studio runs a weekly creative test of six video concepts, keeps the two with the strongest install to day seven retention, and retires the rest.
  • A marketplace runs a geo holdout in three regions to measure how many installs its paid social spend adds beyond organic baseline.

How it is measured

  • Cost per install and cost per acquisition for a defined downstream event
  • Return on ad spend and lifetime value to customer acquisition cost ratio
  • Payback period in days or months, by channel and cohort
  • Retention at day one, day seven and day thirty for acquired cohorts, compared with organic users
