12 Checkout CRO Fixes That Lifted Conversion 34%

Nobody abandons cart because they suddenly stopped wanting your product. They abandon because of friction. Here are the 12 fixes we deploy on almost every store audit — ranked by impact.

1. Enable Shop Pay / Express checkout above the fold

One-tap checkout beats a 4-step form every single time. Mobile conversion typically jumps 10–18% overnight.

2. Kill account creation as a requirement

Guest checkout by default. Offer account creation after the order is placed.

3. Show shipping cost before checkout

Surprise shipping costs are the #1 documented cause of cart abandonment (Baymard Institute).

4. Trust badges near the pay button

SSL, money-back guarantee, real customer count. Not in the footer — where the decision happens.

5. Sticky ATC on mobile PDP

Mobile is 70%+ of traffic. If ATC scrolls off screen, so does your revenue.

6. Real reviews above the fold

Star rating + count in the first 400px. Nothing sells like other buyers.

7. Cart drawer, not cart page

Every extra page load = another chance to bounce. Slide-out cart converts 6–12% better.

8. Order bump on the cart drawer

One relevant add-on at 20–30% off boosts AOV without hurting conversion.

9. Free shipping threshold with progress bar

Nudges AOV up an average of $12–$22 per order.

10. Post-purchase upsell

Zero acquisition cost, converts at 8–15%. It's basically free money.

11. Abandoned cart flow (SMS + email)

Recovers 8–12% of lost carts when done well. Klaviyo + Postscript is the stack.

12. Speed < 2s LCP on mobile

Every extra second of load kills ~7% of conversions. Optimize images, lazy-load, cut apps.
