It sits alongside web design, which is the visual and UX work, and is the discipline commissioned when the brief is to build, ship, and maintain.

Red flags
6 to watch
in any pitch
  • · Refusal to hand over source code ownership or repo access on handover
  • · Proprietary CMS or hosting lock-in that makes migration off the platform painful
  • · Hidden offshoring with no named technical lead and no time-zone overlap
  • · No SLA on bug fixes, no documented post-launch support terms
  • · Can't talk fluently about Core Web Vitals, Lighthouse, or WCAG 2.1 AA accessibility
  • · Suspiciously low fixed-price quotes that skip discovery and assume zero scope creep
