Many AI crawlers do not run JavaScript. Why Won't AI requests up to 10 of your pages as GPTBot, ClaudeBot, PerplexityBot and CCBot, one at a time. It shows what each crawler received. The score has six parts: crawl and render, indexable body copy, intent match, internal linking, demand capture and AI citability. You see the score and the top 3 issues without an account. A free account gives the full report. A remote MCP server lets you run the checks from Claude Code, Cursor or VS Code.
