CrawlCheck

CrawlCheck helps you control what AI discovery engines can access on your site. It audits your robots.txt against 60+ known AI crawlers (including GPTBot, PerplexityBot, ClaudeBot, CCBot, and Google-Extended) to show which bots are allowed versus blocked—so you can avoid accidentally preventing AI apps from finding or citing your pages.

Use the Audit to paste your robots.txt and quickly understand the practical impact of each rule. CrawlCheck also includes tools to help you move from “what’s happening?” to “what should change?”—with a robots.txt generator, a schema generator, and GEO-focused guides that end with concrete checks and copy-paste policy options.

This is designed for founders, SEOs, and developers who want better visibility in AI answers and LLM-driven discovery. It’s especially useful if your robots.txt was created years ago, before AI crawlers were common, or if you’re trying to ensure technical accessibility for generative engine optimization (GEO).

Pricing options include a free scan (no signup) to audit one URL and generate a shareable report with concrete fixes. For deeper coverage, the Pro Deep Report is $49 one-time per site, sweeps up to 50 pages, and provides a prioritized P0–P3 fix list delivered to a private URL.

What is CrawlCheck used for?

CrawlCheck audits your robots.txt for AI crawler access and helps you generate an AI-ready policy. It also includes generators and GEO guides to support changes that improve how AI systems find and cite your content.

How many AI crawlers does CrawlCheck audit?

The tool audits against 60+ known AI crawlers and profiles key bots to show who is allowed or blocked by your current rules.

What’s the free scan, and what does it cover?

The free scan is $0 with no signup. It audits one URL with AI crawler checks and also includes llms.txt and sitemap health, producing a shareable report with concrete fixes.

What does the Pro Deep Report include?

The Pro Deep Report costs $49 one-time per site and can sweep up to 50 pages. It live-tests 8 AI crawlers on every page, catches issues like cloaking, broken pages, and noindex traps, and returns a prioritized P0–P3 fix list to a private URL.

Will blocking GPTBot hurt my Google rankings?

No. GPTBot is for OpenAI model training, while Google Search rankings use Googlebot. Blocking GPTBot doesn’t affect Google Search rankings.

If an AI crawler ignores robots.txt, what should I do?

Treat robots.txt as a request, not a guarantee. For crawlers known to ignore it (such as Bytespider), enforce blocks at the CDN or WAF level using user-agent rules (for example, Cloudflare user-agent rules).
