Frequently asked questions
Is this tool really free?+
Yes, 100% free with no usage limits beyond Google's public API rate limits. We call Google's PageSpeed Insights API directly from your browser — no account, no API key, no data stored on our servers.
How accurate are the results?+
The results come from the same Lighthouse engine that powers pagespeed.web.dev and Chrome DevTools. Scores can vary slightly between runs due to network conditions and server response times — this is normal and expected.
Mobile vs Desktop — which should I test?+
Start with Mobile. Google uses mobile-first indexing, so your mobile performance directly affects search rankings. Desktop scores are typically higher because desktop devices have more CPU and bandwidth — but mobile is what Google evaluates for SEO.
What's a good PageSpeed score?+
Green (90–100) means your page is well-optimized. Orange (50–89) means there are meaningful improvements to make. Red (0–49) means there are critical performance issues that are likely hurting user experience and SEO.
How often should I test my pages?+
Test after every deployment to catch regressions. Run monthly audits on your most important landing pages. If you make significant changes to images, fonts, or third-party scripts, test immediately.
Want automated monitoring?
UpGPT monitors your pages continuously, alerts you to regressions, and tracks Core Web Vitals over time — so you never miss a performance drop.
