Next.js Performance Checklist for Portfolio Sites

Fast websites win trust before the visitor reads a single line.

Quick wins

  • optimize image sizes and dimensions
  • preload only critical assets
  • keep third-party scripts minimal
  • split heavy components

Content strategy

  1. lead with lightweight hero sections
  2. defer non-critical visuals
  3. keep motion smooth but efficient

Measurement

Use Lighthouse and Vercel Analytics regularly after each major update.

Bottom line

Performance is a growth feature, not a technical extra.
