1 in 10 local business websites refuse ChatGPT outright.

The site loads fine in a browser. But when ChatGPT’s crawler asks for the same page, the server returns an error. The business is invisible to AI assistants - and the owner has no idea.

I scanned 91 real US small business sites: 8% refuse a major AI crawler at the server, 26% have no structured data at all. Among small-town and solo operators, 65% had a serious problem.

Dead Zone finds those businesses for you, in bulk, and writes the report that starts the conversation.

What it does

• Scans a domain list, ranks them worst-first
• Tests live access as GPTBot, ClaudeBot and PerplexityBot - catches firewall blocks robots.txt never reveals
• Checks structured data, business markup, address, phone, thin content
• Client-ready HTML reports with YOUR agency name on them
• CSV export you can work like a call sheet

What you get

• The scanner: Node, zero dependencies, no API keys, no subscription
• White-label report generator
• Selling guide: which trades convert, outreach emails, what to charge ($150-2,000 per job)
• Commercial licence, unlimited client sites

You are not pitching “SEO services.” You are showing an owner a closed door on their own website, with the HTTP status code next to it.

Requires Node.js 18+. Tests whether assistants CAN read a business, not whether they currently recommend it. Homepage only.
