1. Missing Machine Signals Detected on plausible.io

  • `/llms.txt` and `/llms-full.txt` return HTTP 404 (AI agents have no structured Markdown index to ingest your product specs or pricing)
  • `/.well-known/ai.txt`, `/ai/summary.json`, and `/ai/faq.json` are all missing (0/4 machine discovery endpoints present)
  • `/robots.txt` does not explicitly allow AI search crawlers (`OAI-SearchBot`, `GPTBot`, `ClaudeBot`, `PerplexityBot`, `Google-Extended`)
  • Homepage JSON-LD is missing `FAQPage` structured entity schemas
