What are the most common website design mistakes businesses make?

The most common website design mistakes include cluttered homepages with no clear hierarchy, CTAs that are buried below the fold, inconsistent typography across pages, and mobile layouts that are compressed rather than redesigned for touch-based navigation. Each of these individually reduces engagement; together they significantly damage conversions.

Other frequent errors include designing without accessibility in mind (violating WCAG 2.1 guidelines), ignoring page speed during the visual design phase, failing to align design with the sales funnel stage a page serves, and not establishing a design system. A design system in Figma with defined tokens for color, spacing, and typography prevents these inconsistencies from accumulating across a growing site.
