User acquisition
Mobile app user acquisition: a practical guide
User acquisition does not begin in an ad account. First, you need to identify the in-app action that creates value, decide what you can pay for that user, and give the algorithm enough reliable data to find more people like them.
What user acquisition includes
User acquisition is often treated as a way to buy installs. That definition misses most of the job. The team is responsible for the path from the first ad impression to an action tied to revenue, such as a trial, purchase, or qualified lead.
A capable UA manager looks beyond CPI. They track store conversion, activation, the cost of a meaningful event, retention, and payback. A cheap install has little value if the user never opens the app again.
Start with economics, not channels
Calculate your allowable acquisition cost before launch. For a subscription app, begin with the contribution margin from a user over a defined period. If LTV data is still weak, use a shorter window and a conservative forecast.
- Record the subscription price, store fees, refunds, and variable costs.
- Measure conversion from install to registration, trial, and payment.
- Set a hard CPA ceiling and a lower operating target that leaves room for error.
- Decide how long the business can wait for payback.
This gives the team a decision framework. A channel with a $3 CPI can be better than one with a $1 CPI if its users buy more often and stay longer.
Measurement before the first ad dollar
An ad system can optimize only for events it receives. A basic setup includes install, first open, registration, trial start, purchase, and revenue. Event names and counting rules should match across product analytics, the MMP, and each ad platform.
On iOS, some data arrives later and in aggregated form. Apple positions AdAttributionKit as a privacy-preserving way to measure installs and re-engagement. Product analytics still matters. The team needs one report that compares ad platform claims with events recorded inside the product.
Run test conversions before launch. Check deep links, currency, purchase deduplication, and time zones. Fixing these issues after traffic starts costs both budget and learning history.
How to choose the first channels
The right starting point depends on the product and the user's intent. Apple Ads captures active demand in the App Store. Google App campaigns distribute ads across Search, Google Play, YouTube, Discover, and other inventory. Meta and TikTok create demand by showing the problem and the product in context.
| Situation | Start with | Reason |
|---|---|---|
| People already search for the solution | Apple Ads and Google | Both can capture existing intent |
| The value becomes clear after a demo | Meta and TikTok | Video explains the use case quickly |
| High price or a complex subscription | Web-to-app and paid social | The web gives more room to explain and sell |
Do not launch every country and channel at once. Start with one understandable market and two traffic sources. That makes it easier to separate a channel problem from a product or creative problem.
A plan for the first 30 days
- Week 1: verify events, store pages, deep links, and reporting.
- Week 2: launch several creative hypotheses with controlled budgets.
- Week 3: stop clear losers, inspect the post-install funnel, and release new variants.
- Week 4: move budget into repeatable combinations and run the first scale test.
Do not judge the account on a single day. Account for conversion delay and learning. Google recommends avoiding disruptive changes during learning, including changes to the optimization event.
When to scale
Scaling begins when performance repeats across several cohorts, not after one unusually good day. Raise budgets in steps and watch whether CPA, payment conversion, and user quality hold.
If the economics break, find the cause. The audience may be exhausted, new volume may come from weaker placements, or the account may simply need fresh creative. UA is a system: measurement reveals the problem, product data explains user quality, and creative opens new demand.
