What the check covers

Seven checks answer engines care about

Answer engine optimization (AEO) starts with access. If AI crawlers can't reach and read your pages, nothing else matters.

01

AI crawler access

robots.txt rules for 15 crawlers behind ChatGPT, Claude, Perplexity, Google AI Overviews & Gemini, Microsoft Copilot, Meta AI, Apple Intelligence and Common Crawl.

02

Readable without JavaScript

Most AI crawlers don't run JavaScript. We measure how much of your homepage is in the raw HTML.

03

Indexable homepage

HTTP status and noindex directives that would keep answer engines away.

04

Structured data

JSON-LD such as Organization that helps AI recognize your brand as an entity.

05

Title and description

The basic signals AI uses to summarize what your company does.

06

XML sitemap

Whether crawlers can discover all of your important pages.

07

llms.txt

An optional plain-text summary of your site written for AI tools.

Built by AGI Search Labs

For mid-size and large B2B companies, crawl access is only the start

We're an AEO and GEO agency working with mid-market and enterprise B2B teams. The free Agent Blindness Report goes well beyond this tool:

  • Your Agent Visibility Score across five dimensions: access, quotability, corroboration, accuracy and share of voice
  • Real buyer prompts on six AI assistants, and the competitors they name instead of you
  • An AI accuracy check: what assistants get wrong about your products, pricing and locations
  • Pipeline at risk, estimated in dollars using your deal size
  • A prioritized fix list. In a paid engagement, our team implements it.

Questions about the instant check

What does the free instant check test?

It reads your public robots.txt and reports whether 15 AI crawlers across 8 AI engines are allowed: ChatGPT (OAI-SearchBot, ChatGPT-User, GPTBot), Claude (Claude-SearchBot, Claude-User, ClaudeBot), Perplexity (PerplexityBot, Perplexity-User), Google AI Overviews & Gemini (Googlebot, Google-Extended), Microsoft Copilot (Bingbot), Meta AI (meta-externalagent), Apple Intelligence (Applebot, Applebot-Extended) and Common Crawl (CCBot). It also checks whether your homepage is indexable, whether its text is readable without JavaScript, and whether you have JSON-LD structured data, a title and meta description, an XML sitemap and an llms.txt file.

Is it really free? Do I need to sign up?

Yes, it's free, with no sign-up and no email required. We only read public files: your robots.txt, llms.txt, sitemap and homepage.

Does a high score mean AI assistants recommend my company?

No. The instant check covers crawl-readiness, which is the first of five dimensions in answer engine optimization (AEO). Being recommended also depends on how quotable your content is, what third-party sources say about you, whether AI describes you accurately, and how you compare with competitors on real buyer prompts. The free Agent Blindness Report covers all five.

Should I block AI crawlers like GPTBot?

It's a business decision. Blocking training crawlers such as GPTBot, ClaudeBot or Google-Extended limits how your content is used to train models. Blocking search and retrieval crawlers such as OAI-SearchBot, Claude-SearchBot, PerplexityBot, Googlebot or Bingbot keeps you out of AI answers altogether. The check shows each crawler separately, so you can see exactly what your robots.txt allows.

Is there a Chrome extension?

Yes. The free LLM Readiness Check extension runs the same crawler checks on any page you open in Chrome, right in your browser, with no data sent to us.
