FAQ

What are Core Web Vitals?
Core Web Vitals are Google metrics measuring user experience: LCP (Largest Contentful Paint) measures loading speed, INP (Interaction to Next Paint) measures interactivity, and CLS (Cumulative Layout Shift) measures visual stability. They directly affect Google search ranking.
How much faster can you make our site?
Most sites see 40-70% improvement. Typical results: LCP from 4s to under 2.5s, load time from 5s+ to under 2s, and Lighthouse score from 40-60 to 90+. Results depend on current state, technology stack, and hosting infrastructure.
Does performance optimization affect SEO?
Directly. Google uses Core Web Vitals as a ranking factor. Faster sites also get crawled more efficiently (improved crawl budget), have lower bounce rates, and higher engagement metrics u2014 all of which support SEO performance.
How do you maintain performance over time?
We implement performance budgets that block deployments if metrics regress, set up automated Lighthouse CI testing, and provide monthly RUM reports. We also review new code changes for performance impact during development.
