Website design optimization through data and color theory

Effective commercial website design relies on measurable user behavior data rather than intuition. Key metrics such as add-to-cart rates and checkout abandonment provide insights into where a site's visual hierarchy or product page information may be failing to convert visitors into buyers.

Beyond data, visual elements like color palettes play a functional role in usability. A successful palette includes primary, secondary, background, text, and accent colors. Designers should prioritize readability by following WCAG contrast guidelines—aiming for at least 4.5:1 for normal text—and ensuring that color is not the sole method of communicating information.
