Multi-Step Form
A form broken into several small screens instead of one long page, so a visitor answers one or two questions at a time.
A multi-step form uses the same psychology as a staircase: one step looks easy, so people start, and having already started, they are more likely to finish than they would be facing every field at once.
Each step should feel like meaningful progress, a visible step counter or progress bar helps, and the questions should get slightly more specific as the visitor moves forward, since a small early commitment makes a bigger later one feel consistent rather than sudden.
The trade-off is total field count: a well-designed multi-step form can ask for more information than a single-page form would ever get away with, but a poorly designed one just adds friction, one more click to abandon at, for every step.
