Cart abandonment is a major challenge for e-commerce businesses. A/B testing the shopping cart and checkout experience can help identify friction points and improve conversion rates.
Instead of guessing what customers want, businesses can test specific changes and measure their impact on checkout completion, conversion rate, and Average Order Value.
What should you A/B test in the cart?
Some useful cart experiments include:
- Transparent pricing: Show shipping costs, taxes, and additional fees earlier.
- Trust signals: Test reviews, guarantees, return policies, and payment logos.
- Cart editing: Make quantity, size, color, and product changes easier.
- Express checkout: Test options such as Shop Pay, Apple Pay, Google Pay, or PayPal.
- Guest checkout: Compare forced account creation with a guest checkout option.
- Sticky checkout CTA: Keep the primary checkout button visible on mobile.
- Delivery information: Test clear shipping options and estimated delivery dates.
- Free shipping progress bars: Encourage customers to increase their basket value.
- Low-stock messaging: Test relevant inventory or urgency notifications.
- Personalized upsells: Compare no recommendations with a single relevant add-on.
Focus on the biggest friction points
The best test depends on where customers are dropping out.
If mobile users have high abandonment, prioritize speed and express payment options. If customers leave when shipping costs appear, test earlier price transparency.
If Average Order Value is low, test incentives such as free-shipping thresholds or relevant product recommendations.
Measure more than conversion rate
A cart experiment should use metrics that match the business objective. Useful metrics include:
- Cart-to-checkout rate
- Checkout completion rate
- Conversion rate
- Average Order Value
- Revenue per Visitor
- Cart abandonment rate
Final takeaway
Cart A/B testing helps e-commerce businesses replace assumptions with evidence. Start by identifying the biggest friction point in your funnel, create a focused hypothesis, and test one meaningful change at a time.
