PRISM Framework · Layer 1: Platform
This tool checks the Platform layer only—how AI engines access your site. It does not check whether AI understands who you are, trusts what you say, or recommends you to anyone. Those are covered in Layers 2–5 of the PRISM framework, and they require a closer look at your specific situation.
Common questions
Check your robots.txt file for GPTBot and OAI-SearchBot directives. If either is listed under Disallow, ChatGPT's crawler is blocked from your site. The PRISM Platform Checker audits this automatically—paste your URL and get an instant result.
GPTBot is OpenAI's web crawler. It retrieves content from websites to power ChatGPT's responses and search features. If your robots.txt blocks GPTBot, your site's content cannot be retrieved or cited by ChatGPT—regardless of how good your content is.
Most accidental AI crawler blocks happened in 2023–2024 when site owners added broad bot-blocking rules to prevent AI training on their content. Those same rules now block the retrieval crawlers that power AI search. It's one of the most common—and most fixable—reasons small businesses are invisible to ChatGPT and Perplexity.
No. Major AI crawlers—including GPTBot, ClaudeBot, and PerplexityBot—do not execute JavaScript. If your site relies on JavaScript to render its content, AI crawlers retrieve a near-empty page. Your site can look polished to a human visitor while being effectively invisible to every AI search engine.
llms.txt is an emerging standard—a plain-text file at your domain root that describes your site's content to AI systems. It has limited adoption by major AI engines currently, and Google has confirmed it does not support it. It's worth adding as a low-cost signal, but it is not a substitute for the foundational platform checks: bot access, crawlability, and HTML-first rendering.
PRISM is a five-layer framework for AI search visibility developed by Aimee Q Devlin. The layers—Platform, Recognition, Intelligence, Signal, Momentum—run in sequence. Platform is the foundation: if AI can't find and retrieve your site, nothing else matters. The full framework covers entity definition, content architecture, third-party validation, and ongoing momentum.
