Hypothesis

Product-page clicks could fall while the path to purchase gets shorter; evaluate completed purchases.

How to run this test

Primary metric

Category-page purchase conversion rate

Compare purchases among visitors who view a listing with the second-image option.

Other metrics

  • Product-card interaction rateTrack how many visitors change the image.
  • Listing add-to-cart rateCheck whether more visitors add from the listing without opening product details.
  • Listing-to-product click-through rateFewer detail visits may mean some questions are answered on the card; read this alongside purchases.
  • Page load timeMake sure extra images do not slow the listing.

What to check before and during the test

  • ChangeAdd a way to switch to a second image on product cards.
  • Keep constantKeep card design, product order, prices and other details unchanged.
  • BehaviorTrack product-page visits and purchases together.
  • DeviceDefine mobile swipe and desktop hover behavior in advance, then review each in its device context; this is not a swipe-versus-hover comparison.
  • Separate testsTest automatic transitions, image count or the type of second image separately.

Setup mistakes to avoid

  1. 1Lazy-load the additional images.
  2. 2Keep image changes user-controlled; test automatic transitions separately.
  3. 3Do not change card size in the same test.
  4. 4Do not show a different color variant as the second image.
  5. 5Make sure swiping does not interfere with page scrolling.
