Frequently Asked Questions

What is a good PageSpeed score?

A score of 90-100 is considered good, 50-89 needs improvement, and 0-49 is poor. Most websites score between 40-70 on mobile. Desktop scores are typically higher because desktop devices have more processing power.

What are Core Web Vitals?

Core Web Vitals are Google's metrics for measuring real-world user experience: LCP (Largest Contentful Paint) measures loading, CLS (Cumulative Layout Shift) measures visual stability, and TBT (Total Blocking Time) approximates interactivity.

Why is my mobile score lower than desktop?

Mobile tests simulate a mid-tier phone on a slow 4G connection. This throttled environment exposes performance issues that are masked on powerful desktop hardware with fast internet.
