# Design Consistency Cheatsheet for eCommerce

A site can look polished and still feel harder to use than it should.

When buttons change, layouts drift, trust cues move around, or forms behave differently from one step to the next, shoppers hesitate.

This practical cheatsheet helps you spot the inconsistencies that quietly reduce trust, add friction, and hurt conversion across the full buying journey.

## Why design consistency matters

Design consistency is not about making everything look nice for the sake of it.

It is about predictability.

When shoppers do not have to keep re-learning how your site works, they move faster, feel safer, and make decisions with less effort.

That is why consistency matters so much for conversion.

This cheatsheet gives you a practical way to review the areas where inconsistency does the most damage, from navigation and product discovery through to cart, forms, trust cues, accessibility, and third-party tools.

### What’s inside the cheatsheet
