Mobile Checkout Optimisation: The Small Fixes With Big Impact

Checkout is where most conversion gains hide

Traffic and product page optimisation get most of the attention, but checkout is frequently where ecommerce brands lose the most conversions — particularly on mobile, where friction is felt more acutely.

Reduce form fields wherever possible

Every additional required field increases the chance of abandonment. Auto-fill support and address lookup tools can meaningfully cut down on manual entry.

Offer express payment options prominently

Shop Pay, Apple Pay, and Google Pay reduce checkout time dramatically compared to manual card entry — and should be visible early in the checkout flow, not buried at the bottom.

Show shipping costs early

Unexpected shipping costs at the final step are one of the leading causes of cart abandonment. Surfacing this information earlier, even as an estimate, builds trust and reduces late-stage drop-off.

Minimise account creation friction

Forcing account creation before checkout adds unnecessary friction. A guest checkout option, with an easy post-purchase account creation prompt, typically converts better.

Test button size and placement on mobile

Small tap targets and awkwardly placed CTAs disproportionately hurt mobile conversion compared to desktop, where precision clicking is easier.

None of these fixes require a platform migration or major redesign — most can be implemented incrementally, and the cumulative impact on mobile conversion is often significant.
