What to check before and during the test

  • Default viewIn the variant, show only differences in the comparison table by default.
  • Keep constantKeep products, feature data, table design and CTAs unchanged.
  • DecisionRead time to decision alongside the target action.
  • AccessKeep all product features available to visitors.
  • Separate testsTest the toggle's design, color or placement separately.

Setup mistakes to avoid

  1. 1Do not hide shared or critical features completely; that could mislead visitors.
  2. 2Make the view-switching control easy to find.
  3. 3Set sample-size and stopping rules before launch; do not stop at the first significant result.
  4. 4Keep the number of products fixed; test only how differences are displayed.
  5. 5Keep the table readable on mobile.
