Publish a real /llms.txt that summarizes the business for AI agents.
State an explicit AI crawler policy in robots.txt for GPTBot, ClaudeBot, Google-Extended and PerplexityBot.
Serve a valid XML sitemap and declare it in robots.txt.
Add schema.org LocalBusiness JSON-LD so machines can read hours, service area and contact details.
Optional: publish a verified agent card at /.well-known/mcp.json so assistants can transact with you directly.
