PageSpeed monitoring
Understanding scores
Performance, Accessibility, SEO, and Best Practices explained.
Overview
PageSpeed monitors run Google Lighthouse and report four scores, each from 0 to 100.
Score categories
- Performance: loading speed and interactivity
- Accessibility: usability for people with disabilities
- Best practices: modern web development standards
- SEO: search engine optimization basics
Score ranges
| Score | Rating | Indicator |
|---|---|---|
| 90-100 | Good | Green |
| 50-89 | Needs improvement | Orange |
| 0-49 | Poor | Red |
Performance is usually the score worth fixing first. It affects what visitors actually experience, and Google uses it as a ranking signal.
