A common conversion optimisation problem
Users abandon your forms halfway
The short answer: start it halfway done. Here is how to recognise this problem in your funnel, why it happens, and how the best consumer apps design it away.
How to recognise it
- Completion falling with every additional field
- Abandonment concentrated at the form's first screen
- Fields asking for things you could infer or defer
Why do users abandon long forms?
People abandon forms at the moment the remaining effort looks bigger than the payoff. An empty ten-field form makes that judgement easy: all cost, visible at once, before any progress exists.
Starting from zero is the psychological killer. Blank fields and a progress bar at 0% say the whole mountain is still ahead.
Most long forms are also honest audits waiting to happen: half the fields exist because a stakeholder wanted them, not because the transaction needs them now.
How do you raise form completion? Start users halfway done
Start the user past zero. Prefill everything inferable: location, sensible defaults, anything they told you before. Count previous actions as progress, so the bar opens at 30%, not empty. Underway beats beginning.
Cut, then cut again: every field must be needed now, not eventually. Anything deferrable moves to after the conversion, where curiosity has flipped to commitment.
Chunk what remains into small screens with visible motion between them: three questions that flow feel shorter than one page of ten.
And end each chunk with momentum language: “nearly there” at 70% is worth more than any redesign of the fields themselves.
The building blocks that solve it
- Momentum Bias: The form opens already underway, never at zero.
- Setup Defaults: Prefill the knowable; let users correct, not create.
Who does this well
TurboTax: Imports and prefills turn a dreaded form into confirming things it already knows: momentum by default.
Uber: Setup asks almost nothing upfront: details arrive one at a time, each at the moment it is needed.
Questions founders ask
Multi-step or single-page forms?
For anything over a handful of fields, small steps with visible progress usually win: each screen is a completable task rather than a wall.
But measure your own: audience and stakes move this one. The principle that holds either way is starting past zero.
Do progress bars actually help?
Honest ones do, especially when they never start at 0% and never lie about what remains.
A bar that crawls or jumps erratically is worse than none: users trade effort against the bar, and a broken bar breaks the trade.
