Slow sites do not just feel bad — they lose rankings and form completions. For service businesses, that is lost pipeline.
What to care about
- LCP — largest contentful paint (often the hero text or image)
- INP — how quickly the page responds to clicks
- CLS — layout shift (jumping buttons kill trust)
You do not need perfection. You need “good” on mobile for your key pages.
Practical fixes that move the needle
- Ship the hero as HTML/CSS first; defer heavy animation
- Compress images; avoid huge hero videos by default
- Limit third-party scripts (chat widgets are expensive)
- Use a modern stack (e.g. Next.js) with sensible caching
- Keep fonts lean with `display: swap`
Design and performance are the same project
A beautiful site that loads in 6 seconds is not beautiful for the visitor who bounced. Performance budgets belong in the design brief.
If your site is a lead engine, treat speed as part of conversion design — not a post-launch chore.
