  • Primary action completion rate

Hypothesis

Showing them together removes that step while making the page longer; it does not guarantee that every testimonial is seen. Compare action completion and actual visibility using the same testimonials.

How to run this test

Primary metric

Primary action completion rate

Compare whether the presentation format changes completion of the target action.

Other metrics

  • Testimonial visibilityMeasure testimonials entering the viewport, including content beyond the first card.
  • Testimonial interaction rateMeasure comparable clicks or scroll behavior in both formats; slider use and visibility are different behaviors.
  • Visibility of the next page sectionCheck whether the open layout pushes important content below the visible area.

What to check before and during the test

  • LayoutUse the same testimonial set and order in a slider and an open layout.
  • VisibilityMeasure viewport entry rather than treating rendered testimonials as seen.
  • Slider behaviorPredefine navigation and autoplay; autoplay is a separate variable.
  • Testimonial countKeep the number and wording of testimonials unchanged.
  • DeviceReview touch and desktop behavior separately; make the slider keyboard-navigable and autoplay stoppable.

Setup mistakes to avoid

  1. 1Do not use an autoplaying slider that cannot be stopped.
  2. 2Do not change presentation format and testimonial count together.
  3. 3Keep a clear indicator that more testimonials can be browsed.
  4. 4Investigate why visibility fell before accepting a lift in the target action.
  5. 5Respect reduced-motion preferences in transitions.
