Why Website Performance Matters
A slow website costs you customers. Studies show that 53% of mobile users abandon sites that take longer than 3 seconds to load. Google also uses page speed and Core Web Vitals as ranking factors, meaning slow sites rank lower in search results.
The 4 Categories We Grade
- Performance: Page load speed, time to interactive, largest contentful paint, and cumulative layout shift
- Accessibility: Screen reader compatibility, color contrast, keyboard navigation, and ARIA labels
- Best Practices: HTTPS, safe JavaScript, image optimization, and modern web standards
- SEO: Meta tags, crawlability, mobile-friendliness, and structured data

Frequently Asked Questions
What does this tool measure?
We use Google's PageSpeed Insights API (the same data behind Lighthouse) to measure Performance, Accessibility, Best Practices, and SEO. Scores range from 0-100, with 90+ being excellent.
Why is mobile score usually lower than desktop?
Mobile testing simulates a mid-range device on a slower network connection. This more closely represents how most users experience your site, since over 60% of web traffic is mobile.
What's a good score?
90-100 is excellent (A), 70-89 needs improvement (B/C), and below 70 is poor (D/F). Most well-optimized business sites score 80+ on desktop and 60+ on mobile.
How can I improve my scores?
Common improvements include optimizing images, enabling compression, minimizing CSS/JS, using a CDN, implementing lazy loading, and ensuring proper caching headers. The tool shows your specific opportunities.
Does page speed affect Google rankings?
Yes. Google confirmed that Core Web Vitals (which include page speed metrics) are a ranking factor. Faster sites rank higher, get more traffic, and have better conversion rates.
