# AI Crawlability Test — Free Crawlability Checker & Crawl Test Tool

Free website crawlability checker and AI crawl test tool — check whether your website has the key files AI crawlers and agents look for.

## What it checks

**llms.txt** — The emerging AI-readable site manifest that tells LLMs how to interact with your site. Introduced at llmstxt.org, it provides a structured overview of your site's content for AI agents.

**robots.txt** — Standard crawl-control file. Verifies it exists and parses directives including `User-agent: *`, `Disallow`, `Allow`, and `Sitemap` entries. Also checks that AI crawlers (GPTBot, ClaudeBot, PerplexityBot) are explicitly permitted.

**sitemap.xml** — Checks for a sitemap across common paths and via any `Sitemap:` directive declared in robots.txt.

**Structured data** — Validates JSON-LD schema markup, Open Graph tags, and canonical URLs so AI agents can understand your content.

**Performance & structure** — Measures server response time, compression, HTML heading hierarchy, and internal linking depth.

## How to use

Enter your website's URL (e.g. `yourwebsite.com`) and click **Check site**. The crawlability checker runs instantly — each file is checked live against your site in real time, not from a cache. You receive a scored crawlability audit graded A–F with specific fix recommendations for every failing check.

## Why crawlability matters

ChatGPT, Claude, Perplexity, and AI-powered browsers are rapidly replacing traditional search as the way people find information. Running a regular **crawl test** on your site ensures AI crawlers can discover and cite your content. If your website isn't structured for AI crawlers, you risk becoming invisible — even if you rank well on Google today.
