Why performance is a growth lever
Page speed is not just an engineering metric. It directly impacts search visibility, conversion rate, and paid media efficiency.
The three-part audit
- Rendering bottlenecks: identify slow server or client rendering paths.
- Asset weight: reduce JavaScript, image payload, and unused CSS.
- Interaction friction: improve input responsiveness and visual stability.
Fast wins
- Prioritize route-level code splitting.
- Serve responsive images and modern formats.
- Move non-critical scripts behind user interaction.
