Why Your Lighthouse Score Doesn't Matter (And What Does)

The Lighthouse Trap

Every agency chases 100. Every client asks for it. But here's the thing: a perfect Lighthouse score doesn't correlate with revenue.

We've seen sites with 98+ scores convert worse than 75-score sites. Why? Because Lighthouse measures mechanical performance, not user experience or business outcomes.

What Actually Matters

• First Input Delay (FID) — How fast users can interact with your site
• Conversion Rate — The only metric that pays the bills
• Bounce Rate by Device — Mobile visitors leave fast on slow sites
• Core Web Vitals — Real user metrics from actual traffic

Our Approach

We optimize for business metrics first, Lighthouse second. If your 95 score converts 40% better than a competitor's 100, you win. That's the standard behind our Next.js development service — and why our e-commerce clients see revenue triple, not just scores climb.
