See what AI bots miss when they can't execute JavaScript on your pages
AI bots read the raw HTML, not the rendered page. If your content loads through JavaScript, ChatGPT and Perplexity may see a near empty page. This free check shows you the gap in seconds.

Why Check GEO Crawlability?
AI bots like GPTBot, ClaudeBot, and PerplexityBot don't execute JavaScript. If your website relies on JS to render content, these bots see a stripped-down version of your page, missing text, meta tags, links, and structured data. This tool shows you exactly what they're missing.

Crawlability is the foundation of AI visibility
AI answer engines like ChatGPT, Perplexity, Google AI Overviews, and Gemini build their answers from the HTML they can fetch. Most of these crawlers do not execute JavaScript, so any content your site renders client side is invisible to them. If GPTBot or PerplexityBot cannot read a paragraph, that paragraph can never be cited, quoted, or summarised in an AI answer.
This free checker fetches your page exactly the way an AI crawler does and compares it against the fully rendered browser version. You see, line by line, which headings, paragraphs, links, and structured data the bots are missing, so you can close the gaps before they cost you visibility in generative search. If a crawler cannot fetch the page at all, check your robots.txt for AI bots first, then run ongoing audits with GEO optimization in LLM Pulse.
How the GEO Crawlability Checker works
Fetch as a bot
We request your page with a plain HTTP fetch, the same way GPTBot, ClaudeBot, and PerplexityBot read the web without running JavaScript.
Render as a browser
We load the page a second time with full JavaScript rendering, capturing everything a human visitor would see.
Compare and score
We diff the two versions and grade your crawlability, highlighting the exact content AI engines cannot see.
What the crawlability report reveals
Every report breaks down the gap between what bots fetch and what browsers render, so you know precisely what to fix for AI search.
Content parity
The share of your visible text that survives without JavaScript, the single biggest factor in whether AI engines can quote your page.
Meta and title tags
Whether your title, description, and canonical tags live in the raw HTML or get injected too late for crawlers to read.
Links and navigation
Internal and external links that only appear after JavaScript runs, cutting off the paths AI crawlers use to discover your other pages.
Structured data
Schema markup and rich metadata that may be missing from the static response, weakening how machines understand your content.
How it works
How the GEO crawlability checker works
We fetch your page the way an AI bot does, then compare it to a full browser render to reveal what is missing.
Enter your page URL
Paste the URL you want to test and submit. We start by fetching the raw HTML exactly the way AI crawlers and search bots do.
We render it both ways
We load the same page a second time with full JavaScript rendering, like a browser, then compare the two versions side by side.
See what AI bots miss
You get a content diff showing the text, headings, links, meta tags, and structured data that only appear after JavaScript, plus fixes to make them visible.
Frequently Asked Questions
How does this tool work?
We fetch your page twice, once as a static HTTP request (like AI bots do) and once with JavaScript rendering (like browsers do). We then compare the two versions to show you exactly what content, meta tags, and links AI crawlers are missing.
How long does the analysis take?
The analysis usually takes 15-30 seconds. We need to fetch the page twice and render JavaScript, which takes slightly longer than a simple fetch.
What if my site is a SPA?
Consider implementing Server-Side Rendering (SSR) or static site generation. Ensure critical meta tags, headings, and structured data are included in the initial HTML response, not injected by JavaScript.
