Site Speed Basics: Quick Wins

How to get immediate performance gains with minimal effort.

Compress images (WebP/AVIF) and set width/height to avoid layout shifts.

Use system fonts or one font weight. Defer non-critical scripts and avoid heavy libraries.

Cache static assets with long max-age; version files using hashes or file names.

Minify CSS and JS after you finish iterating.

Audit with Lighthouse and fix the top issues first.
