Hypothesis

A multi-step form divides the same work into smaller screens, reducing the initial density but adding navigation. Compare fixed flows with the same fields and a clear indication of what remains.

How to run this test

Primary metric

Qualified opportunities per assigned visitor

Compare qualified opportunities per eligible visitor assigned to each form layout, using the same qualification rule and follow-up period.

Other metrics

  • Drop-off by stepFor the multi-step form, report where visitors leave; map the equivalent fields in the single-page form.
  • Form completion timeMeasure time among visitors who start the form and report non-completions separately.
  • Qualified opportunity rateCompare qualified opportunities among all eligible assigned visitors over the same follow-up period.
  • Form return rateAmong visitors who leave a form incomplete, compare returns within the same defined window.

What to check before and during the test

  • StructureCompare a single-page form with a predefined multi-step grouping.
  • Early fieldsKeep field order logical and review early drop-off.
  • ProgressUse a clear, accurate progress indicator in the multi-step version.
  • GroupingKeep the same fields in both versions and define the step count before launch.
  • DeviceReview mobile and desktop separately.

Setup mistakes to avoid

  1. 1Keep a progress indicator so users know where they are.
  2. 2Use only the steps required by the predefined grouping; there is no universal ideal step count.
  3. 3Allow users to go back without losing their entries.
  4. 4Keep step count and grouping fixed throughout the test.
  5. 5Keep field order and required status consistent.
