Speed is a feature. A fast site feels trustworthy, ranks better and costs less to run. Here is the short checklist we run through on every project before launch — none of it is exotic, and all of it matters.
The checklist
- Serve pages from the edge cache, and purge on publish
- Ship modern image formats with proper
srcsetandsizes - Keep JavaScript off pages that don’t need it
- Preload the hero image and the main font
- Measure with real-user data, not just lab scores
Budgets we hold ourselves to
| Metric | Target | Why |
|---|---|---|
| Largest Contentful Paint | < 1.8 s | The page looks ready |
| Interaction to Next Paint | < 150 ms | Taps feel instant |
| Cumulative Layout Shift | < 0.05 | Nothing jumps around |
| JavaScript on articles | < 50 kB | Reading needs no framework |
A tiny example
<link rel="preload" as="image" href="/hero-1024.avif" fetchpriority="high">The fastest request is the one you never make.
