Web design covers look and user flow: layout, colors, typography, wireframes. Web development is technical implementation: HTML, CSS, JavaScript, backend, databases, hosting.

UX design (user experience) sits between: how does usage feel? Where does the user click? UI design is the visual surface. In practice roles overlap — but responsibilities differ.

When you need what

Design only (mockups/Figma): if you have developers to implement. Development only: if design and content are ready. Both: for most mid-size projects — especially when SEO, performance, and conversion matter1Google: SEO Starter Guide.

A beautiful Figma file without solid implementation stays a picture. Code without thoughtful design delivers function, not conversion.

Common mistakes

Design and development from different agencies without alignment
Pixel-perfect mockups that are expensive or slow to build
SEO only after launch — instead of from day one
No shared scope: what is in the design price vs. dev price?
Mobile as an afterthought instead of mobile-first

Better: one team or agency that delivers design and development together — or clear interfaces and a shared brief.
