Performance Optimizations for Small Sites

Practical performance improvements that give the biggest user-facing wins for small websites.

By Noah Hunt2025-01-181 min

Small sites don't need complex instrumentation to feel fast. Focus on the largest wins that are simple to implement.

Priority list:

  1. Image sizing: serve appropriately sized images and use modern formats (AVIF/WebP where supported).
  2. Critical CSS: inline minimal critical styles for above-the-fold content.
  3. Limit third-party scripts: each adds latency and potential layout shift.
  4. Defer nonessential JS and hydrate interactive parts only when necessary.

Tooling: Lighthouse for a quick audit; next/image or an image CDN to automate responsive images; prefetch/preload for critical assets.

Measure before and after: pick a slow page, apply one change, and measure perceived speed improvements.
