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.
