Zuko: multi-step forms only outperform single-page above ~7 fields; below that, neutral or worse

Claim: Zuko (form analytics vendor) reports that a two-step form outperforms a single-page form by 14% only when total fields exceed seven. Below that threshold, the multi-step lift is neutral or negative.

Confidence: Single-source.

The pragmatic threshold for Candid client work: Below 7 fields, ship the form as single-step. The multi-step pattern adds clicks and friction for no measurable benefit at short lengths.

Above 7 fields, split — with the most useful first step often being a routing question (vertical selector, urgency selector) that lets the SMB pre-qualify the lead even if the user abandons step 2. This is where the multi-step pattern earns its keep for a multi-vertical service business: the value is internal lead routing, not dramatic conversion lift on the form itself.

Used in: RULE: Forms under ~7 fields stay single-step. Multi-step only when total fields cross the threshold..
