Hypothesis

They can clarify expectations, but may also change who decides to buy. Keep review text and order the same in both arms, then compare returns after an adequate follow-up period.

How to run this test

Primary metric

Return rate

Compare returns for orders that have completed the same follow-up period in each arm, alongside conversion and the mix of products purchased.

Other metrics

  • Purchase conversion rate (CR)Assess purchases among all assigned visitors, not only those who open a photo.
  • Review section interaction rateUse photo opens and review interactions as diagnostics; those controls appear only in the variant.
  • Page weight and load timeMake sure images do not slow the mobile experience.
  • Moderation workloadCheck that the volume of inappropriate content remains manageable.

What to check before and during the test

  • PhotosShow permitted customer photos within the same eligible reviews.
  • FormatUse one fixed photo presentation and keep review order unchanged.
  • CollectionKeep the review request process unchanged; prompting for new photo submissions is a separate test.
  • Image setSet eligibility rules and a maximum number of displayed photos.
  • CategoryReview relevant categories separately.
