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.
