Lighthouse SEO Report
Run a Lighthouse audit to check your site's performance, accessibility, SEO, and best practices scores.
What Is Lighthouse?
Lighthouse is an open-source, automated tool for improving the quality of web pages. You can run it against any web page — public or requiring authentication. It has audits for performance, accessibility, progressive web apps, SEO, and more.
Lighthouse Score Categories
| Category | What It Measures |
|---|---|
| Performance | How fast the page loads and becomes interactive. Includes First Contentful Paint, Speed Index, Largest Contentful Paint, and more. |
| Accessibility | How usable the page is for people with disabilities. Checks color contrast, ARIA attributes, keyboard navigation, and semantic HTML. |
| Best Practices | Whether the page follows modern web development best practices. Includes HTTPS, correct image aspect ratios, no console errors, and more. |
| SEO | Whether the page is optimized for search engines. Checks viewport meta tag, document title, meta description, link text, image alt attributes, and more. |
| Progressive Web App | Whether the page meets the baseline PWA checklist. Includes service worker, manifest, HTTPS, and more. |
