Free AI crawlability tool

AI Crawlability Checker

See how much of your content AI crawlers can read without JavaScript — before they decide whether to quote you. Free, instant, no signup.

Can AI crawlers actually read your site?

Most AI crawlers don't run JavaScript. If your content renders client-side, bots like GPTBot and PerplexityBot see an empty shell — no text to quote, no headings to parse. Your site can look perfect in a browser and be invisible to AI. This free tool fetches your page the way AI bots do and scores what they can see.

What the check looks at

  • How much content renders in the raw HTML without JavaScript.
  • Whether headings, title and meta description are server-rendered.
  • Whether there are links AI crawlers can follow to your other pages.

Readable is the floor, not the ceiling

Being crawlable means AI can read you. Being recommended means it chooses to. Visiblee tracks whether ChatGPT, Gemini and Perplexity actually mention your brand across the prompts your buyers ask — once your content is visible to them. Fix crawlability above, then run a free scan.

Frequently asked questions

What does the AI Crawlability Checker do?

It fetches your page exactly as most AI crawlers do — raw HTML, no JavaScript — and scores how much of your content they can actually see. Sites that rely on JavaScript to render content often look great in a browser but are nearly empty to AI bots.

Is it free?

Yes — enter your website for an instant crawlability report, no signup.

Why does JavaScript rendering matter for AI?

Most AI crawlers (GPTBot, PerplexityBot, ClaudeBot and others) don't execute JavaScript. If your content is rendered client-side, they see an empty shell — no text, no headings, nothing to quote. Server-rendering or pre-rendering your key content makes it visible to AI.

How is the crawlability score calculated?

We check how much text renders without JavaScript, whether headings, title and meta description are in the raw HTML, and whether there are links AI bots can follow. The weighted result is your AI crawlability score.

What if my score is low?

A low score usually means a single-page-app or heavy client-side rendering. Server-side rendering (SSR), static generation, or pre-rendering for bots will make your content visible to AI crawlers. Fix that first — it's foundational.
