How to use the PageSpeed Insights
What it does
PageSpeed Insights analyzes how fast a single page loads and how stable it feels to real users. It reports Core Web Vitals such as LCP (Largest Contentful Paint), CLS (Cumulative Layout Shift), and INP (Interaction to Next Paint), plus lab metrics and specific opportunities to speed the page up.

Reading the results
The headline performance score runs from 0 to 100. Green is good, orange needs work, and red is poor. Below it, each Core Web Vital is marked pass or fail against Google's thresholds. The Opportunities list estimates how much load time you could save, for example by compressing images, deferring unused JavaScript, or serving next-gen formats. Fix the highest-savings items first, then re-test to confirm the gains. Mobile scores are usually lower than desktop, so treat mobile as your baseline.
Credits
PageSpeed Insights is free and costs 0 credits. Test individual pages as often as needed. Tip: test both a template page and a content page, since they often have very different performance profiles.
