Why Glook wins vs Google PageSpeed Insights
Security audits PageSpeed doesn't have — CSP, HSTS, SSL Labs TLS grading, cookie flags, secrets detection, and 15+ HTTP security checks.
AI visibility coverage — llms.txt, per-bot crawler access (GPTBot, ClaudeBot, PerplexityBot), schema.org, and trust signals. PageSpeed only measures performance.
AI fix prompts — every issue generates a ready-to-paste prompt for Cursor or Claude Code. PageSpeed shows scores but no actionable code fixes.

Common questions about Glook vs Google PageSpeed Insights
If PageSpeed Insights is free, why use Glook?
PageSpeed Insights only measures performance (Lighthouse scores and Core Web Vitals). Glook also audits security headers, AI visibility, SEO tags, schema.org, and trust signals — plus generates AI fix prompts for every issue so you can paste fixes into Cursor or Claude directly.
Does Glook use Google's real CrUX data?
Yes. Glook pulls Chrome User Experience Report (CrUX) data for real-world Core Web Vitals alongside a full Lighthouse audit. You get both lab data and real-world field data in one report.
