Open your app like a total newbie. No YouTube reviews, no context. From cold install to first meaningful action: how many users get there in minute 1?
Define the action first: first message sent, first gem matched, first photo uploaded, whatever reveals the core value.
Common failure patterns I find
- Feature dump on the home screen, no guidance.
- No sample content to tap and try.
- Vague or competing CTAs.
- Account creation before any value is shown.
The rule of thumb
If fewer than 40% of new users hit the action you want, fix onboarding before you spend another cent on UA.
Recent example: I opened an AI writing app and felt lost. No sample text to edit, no “try this” button, just empty fields and upgrade prompts. They were spending $10K a month on Meta to drive people into confusion.
Paid traffic amplifies whatever your first minute already does. If that minute converts, spend scales it. If it confuses, spend just buys more confusion.
