Reviews are part of the decision, not a footnote. If social proof is hard to find, its value drops.

Before customers click the final payment button, show them exactly what they’re buying, paying, and receiving.

The thank you page should confirm the purchase and guide the next step, not just act as a dead-end receipt.

Customers should be able to update quantities or remove items quickly. A cart that resists change resists conversion.

A visible threshold for free shipping or a reward can turn “almost” into action.

When returning visitors come back, their cart should still be there. Saved intent is easier to convert than rebuilt intent.

When a checkout form shows an error, the customer’s details should still be there. Errors should interrupt, not erase.

Forcing account creation before checkout adds friction at the exact moment the customer is ready to buy. Guest checkout keeps the path open.

Some customers are one unanswered question away from leaving. Make help available on the product page.

Delivery timing is part of the product decision. Customers should not have to guess when their order will show up.
