Frequently Asked Questions

What are Core Web Vitals and why do they matter?

Core Web Vitals are Google's metrics for user experience: LCP (loading), INP (interactivity), and CLS (visual stability). Since 2021, they directly impact search rankings. Poor scores mean lower visibility in search results.

How much can performance optimization improve my site?

Most sites see 30-50% improvement in load times and move from failing to passing Core Web Vitals. The exact improvement depends on current issues, but we guarantee measurable results.

Will optimization break anything on my site?

No. We thoroughly test all changes in staging before deploying. We focus on safe, proven optimizations and document everything we change.

How long does a performance audit take?

A comprehensive audit takes 1-2 weeks. Implementation of fixes varies based on the issues found, typically 2-4 weeks for a full optimization project.
