What is a good Core Web Vitals score?

Google considers an LCP under 2.5 seconds (I target under 1.2s), an INP under 200ms, and a CLS under 0.1 to be "Good". Passing all three metrics is required for ranking advantages.

Can you speed up my website without changing its visual design?

Yes. In most cases, performance bottlenecks stem from unoptimized assets, render-blocking scripts, and inefficient code execution rather than the visual design itself.

Do you provide before and after speed comparison reports?

Yes. Every performance engagement includes clear before-and-after Lighthouse and Core Web Vitals metrics.
