How can I check if AI bots can even read and index my website content properly?
Check three things: whether your robots.txt allows the AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended and others), whether your important content renders in the raw HTML rather than only via JavaScript, and whether your pages expose clear text, headings and structured data the model can parse. A GEO readiness check — like the free one in CiteLens — fetches your site as these bots would and reports exactly which of these are passing or blocking you.
Key takeaways
- Check robots.txt for the AI bots: GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot.
- Make sure key content is in the server-rendered HTML, not only injected by JavaScript.
- Expose clear headings, readable text and structured data (schema.org) so models can parse facts.
- A GEO readiness check fetches your site as the bots do and flags access or rendering problems.
The three gates AI bots pass through
Access: AI crawlers identify themselves with user-agents like GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot, Google-Extended and CCBot. If your robots.txt disallows them, you've opted out of being read — sometimes unintentionally, via a blanket rule. Rendering: many models read mostly the initial HTML, so content that only appears after JavaScript runs can be invisible to them.
Parsing: even readable pages vary in how easy they are to extract. Clear headings, plain-text statements of fact, and structured data (schema.org) make your claims easy to lift into an answer; walls of text, facts trapped in images, and ambiguous phrasing make them easy to skip.
How to test it quickly
Fetch your page the way a bot would — view the raw HTML source and confirm your key facts are present without running scripts; read your robots.txt and confirm the AI user-agents aren't disallowed; check that you have real headings and, ideally, schema markup. Do this for your most important pages, not just the homepage.
CiteLens includes a free GEO readiness check that automates all of this: it requests your site as the AI crawlers, reports whether each is allowed, whether content is reachable without JavaScript, and whether your structure and metadata are parseable — turning a vague worry into a specific checklist.

Frequently asked questions
Which AI bots should my site allow?
The main ones are GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot, Google-Extended (Google) and CCBot (Common Crawl). Allowing them lets your content be read for AI answers; blocking them opts you out.
Does JavaScript hurt AI visibility?
It can. If your important content only appears after JavaScript executes, some AI crawlers may not see it. Server-rendered or static HTML for key facts is safest.
How do I check crawlability for AI?
Inspect robots.txt and your raw HTML, or run a GEO readiness check like the free one in CiteLens, which fetches your site as the AI bots and reports access, rendering and structure issues.
