Frequently Asked Questions

What is a good PageSpeed score?

Google Lighthouse rates 90-100 as good (green), 50-89 as needs improvement (orange), and below 50 as poor (red). Aim for 90+ on both mobile and desktop, since mobile scores are typically lower due to slower network/CPU simulation.

Why is my mobile score lower than desktop?

Lighthouse simulates mobile tests on a throttled mid-tier device with a slower simulated network connection, closely matching real-world mobile conditions. Desktop tests use faster simulated hardware and network, so scores are usually higher.

What are Core Web Vitals?

Core Web Vitals are Google's official user-experience metrics: LCP (loading speed), CLS (visual stability), and INP/TBT (interactivity/responsiveness). They've been a confirmed Google ranking signal since 2021.

How is this different from Google's own PageSpeed Insights site?

This tool calls the same official Google PageSpeed Insights API and Lighthouse engine Google's own site uses, so the scores and metrics you see here are identical — just presented with both mobile and desktop results together.

Why does the test take 10-15 seconds?

Each test runs a real, full page load through Google's Lighthouse engine — fetching every resource, executing JavaScript, and measuring rendering timings — for both mobile and desktop. That real-browser simulation is what takes time, but it's also what makes the results accurate.

What's the fastest way to improve my score?

Start with the highest-impact items in the Opportunities & Diagnostics table above — usually image compression, enabling GZIP/Brotli compression, minifying CSS/JS, and reducing third-party scripts. Fix the top few items first; they typically account for most of the score gap.
