When to use each
Choose Lighthouse if you need a quick single-page performance check, accessibility auditing, or PWA validation. It's free, developer-focused, built right into Chrome, and works one page at a time with no signup needed.
Choose AuditZap if you need site-wide auditing across multiple pages, AI-powered fix instructions ranked by estimated revenue impact, client-ready PDF reports, ongoing monitoring, and SEO-focused checks that Lighthouse doesn't cover — like broken links, OG tags, and structured data validation.
General guidance vs specific fix instructions
Lighthouse provides general best-practice recommendations. AuditZap adds site-specific fix instructions tailored to your CMS.
Lighthouse (example)
Largest Contentful Paint (5.2s)
Ensure the largest contentful element loads quickly. Consider reducing server response time, removing render-blocking resources, and optimising images.
AuditZap (example)
Largest Contentful Paint (5.2s)
“Your hero image (hero-banner.jpg, 1.8 MB) is the LCP element. Convert it to WebP, resize to 1200px wide, and add loading="eager" + fetchpriority="high". Also move the Google Fonts <link> to a preload tag. Expected improvement: ~2.5s.”
