Web Design is the discipline of designing websites so they are visually effective, usable, accessible, and aligned with business goals.
It matters because a website is often the first serious evaluation point for a buyer. Good design reduces confusion, builds trust quickly, supports accessibility, and helps visitors take the next step without feeling pushed.
Example
A contractor’s web design might use project photographs beside the relevant services, a readable navigation menu and a short inquiry form. Together, those choices determine how the business is presented and how visitors move through the site.
