What a healthy mobile UA funnel looks like in 2026

Most mobile growth problems are not really acquisition problems - they are funnel problems wearing an acquisition costume. Before you change a bid or a budget, it helps to know what a healthy funnel actually looks like, stage by stage, so you can see where yours is leaking.

Think in stages, not in installs

An install is a milestone, not a goal. The funnel that matters runs from impression to click to install to activation to retention to revenue. Spend leaks at every join, and the leak you can least afford is usually the one furthest down - because that is the spend you have already paid for.

The benchmarks worth holding yourself to

• Click to install: if your store page converts well below the category, the cheapest win is often ASO, not a lower bid.
• Install to activation: the share of new users who reach your "aha" moment in the first session is the single best early signal of campaign quality.
• Day-7 and day-30 retention: retention is the ceiling on what UA can profitably spend. If it is weak, no amount of clever buying fixes the maths.

Where the spend actually leaks

In our experience the three most common leaks are a store page that converts the paid traffic poorly, an onboarding flow that loses users before they reach value, and measurement so noisy that the team optimises toward the wrong events. Fix those and the same media budget simply works harder.

What to do this week

Map your own funnel against the stages above and find the single biggest drop. That is your highest-leverage project - and it is almost never "spend more".
