One of the best-measured facts on the web: 1 second of extra load time means up to 7% fewer conversions (Akamai). A slow site doesn't just annoy people — it quietly sends your customers back to Google, and from there to a competitor.
What actually makes a site fast
Not magic — engineering decisions made at the very start:
- Static-first rendering. Pages are computed ahead of time and served as ready-made HTML — the browser never waits for a server to "think".
- Custom code instead of heavy templates. No 40 plugins and megabytes of third-party JavaScript downloaded on every visit.
- Discipline with images. Modern formats, correct sizes, and lazy loading for everything below the first screen.
- Animations that cost nothing. Motion running on the browser's compositor, not the main thread — striking, without stutter.
How we measure it
Google scores websites with Core Web Vitals — how fast content appears, how quickly the page responds, and whether it jumps around while loading. Those are the exact metrics we track on every project, because they feed directly into rankings.
