How to Use the Page Speed Audit Checklist

This comprehensive audit checklist covers the four pillars of web page quality: Performance, SEO, Accessibility, and Best Practices. Go through each item, test your page, and mark items as pass, warning, or fail.

Performance items focus on Core Web Vitals (LCP, FID, CLS) and general loading optimization. These directly impact user experience and search rankings.

SEO checks ensure your page is properly optimized for search engine discovery and indexing. Meta tags, structured data, and mobile-friendliness are all critical factors.

Accessibility items ensure your site is usable by everyone, including people using assistive technology. Meeting WCAG 2.1 AA standards is both good practice and often a legal requirement.

Use the export feature to save your audit report and track improvements over time. Re-audit after making changes to see your scores improve.
