1) Why speed affects leads
Most service-business traffic is mobile. If your page takes too long, people hit back and pick the next option. Speed impacts:
- Drop-off: fewer people reach your CTA
- Trust: slow feels outdated or sketchy
- Conversion: forms get abandoned more often
2) What usually makes sites slow
- Huge images (full-resolution photos served to phones)
- Too many third-party scripts (chat widgets, trackers, heavy embeds)
- Large JS bundles for simple pages
- Unoptimized fonts and icon libraries
- No caching/CDN strategy
3) Quick wins that matter
Compress and size images
- Use modern formats (WebP/AVIF when possible)
- Don’t ship a 4000px image into a 900px container
- Lazy-load below-the-fold images
Be selective with scripts
- Every extra script is a performance tax
- Remove anything that doesn’t clearly increase leads
- Defer non-critical scripts
Keep mobile interactions lightweight
- Avoid heavy sliders and giant animations
- Prefer clean CSS effects over JS-heavy components
A simple lead-gen site should feel “instant” on a phone. If it doesn’t, the site is leaving money on the table.
4) How to measure (simple)
You don’t need to become a performance engineer. Start with:
- Run Lighthouse (Chrome DevTools → Lighthouse)
- Test on a phone over cellular if possible
- Watch for: oversized images, render-blocking resources, and unused JS
5) Quick speed checklist
- Images are compressed + correctly sized
- Below-the-fold images use lazy loading
- Minimal third-party scripts
- Fonts are not excessive
- JS is defer/async where appropriate
- Site feels fast on a phone
