Why Glook wins vs GTmetrix
Security audits GTmetrix doesn't have — CSP, HSTS, SSL Labs TLS grading, cookie flags, open .env, and 15+ more HTTP security checks.
AI visibility coverage — llms.txt, per-bot crawler access (GPTBot, ClaudeBot, PerplexityBot), schema.org citability. GTmetrix is performance-only.
AI fix prompts for every issue — paste directly into Cursor or Claude Code. GTmetrix shows waterfall charts but no actionable code fixes.
