Hypothesis

Making the existing options more visible beside the product price may surface them earlier. This test changes the emphasis of the information, not the financing offer or the primary price unit.

How to run this test

Primary metric

Revenue per visitor (RPV)

Use revenue per visitor as the primary metric, even if installment visibility increases conversion.

Other metrics

  • Purchase conversion rate (CR)Read purchase rate alongside revenue per visitor.
  • Average order value (AOV)Check whether visitors shift toward higher-priced products.
  • Installment selection rateMeasure whether shoppers actually choose installments.
  • Cancellation and return rateTrack cancellations and returns over the same period in both arms.

What to check before and during the test

  • EmphasisApply one predefined visual emphasis to the installment information near the price.
  • PlacementKeep the chosen placement fixed throughout the test.
  • FormatChoose text or an icon before launch; do not compare both in this test.
  • CheckoutKeep payment-step information and available installment plans unchanged.
  • DeviceReview the same change on mobile and desktop.

Setup mistakes to avoid

  1. 1Show installment terms only when they apply to the product.
  2. 2Do not make the message so large that it overwhelms the price.
  3. 3Keep prices and discounts unchanged during the test.
  4. 4Check mobile layout for shifts or overlap.
  5. 5State any financing cost when quoting installment amounts.
