Hypothesis

This shortcut may help them buy, but less product review could also lead to incorrect choices and returns.

How to run this test

Primary metric

Order completion rate

Compare orders among eligible visitors assigned to the quick add-to-cart experience.

Other metrics

  • Add-to-cart rateCheck whether adding from the listing increases.
  • Time to purchaseCompare time to purchase using the same start definition and observation window.
  • Return rateTrack returns for all completed orders over the same follow-up period, not only orders added quickly.
  • Listing-to-product click-through rateDetail-page visits may decline; read this alongside conversion and returns.

What to check before and during the test

  • ShortcutAdd a quick-add button to product cards while preserving required variant selection.
  • Keep constantKeep prices, stock, variant structure and product-detail CTAs unchanged.
  • UsageTrack button use and subsequent purchases.
  • SelectionReview abandonment when size, color or another required option must be selected.
  • CategoryIf sample size allows, review standard products separately from categories that require a selection.

Setup mistakes to avoid

  1. 1Do not add products to the cart before required variants are selected.
  2. 2Keep the button's position and size from disrupting the listing.
  3. 3Keep stock information and variant structure unchanged.
  4. 4Do not use quick add as a replacement for the product-detail CTA.
  5. 5Show clear confirmation after an item is added.
