What is an AEO checker?

Search is splitting in two. Alongside the classic ranked-link results, a growing share of discovery now happens inside AI answer engines — ChatGPT, Claude, Perplexity, and Google’s AI Overviews. Answer Engine Optimization (AEO) is making sure those engines can find, understand, and cite your content. This tool audits the technical readiness that decides whether you’re eligible to be cited.

What this tool checks

  • AI-crawler access — are GPTBot, ClaudeBot, PerplexityBot, Google-Extended and CCBot allowed?
  • llms.txt — do you publish an AI-agent guide to your best content?
  • Structured extractability — clean semantic HTML and schema an AI can parse and attribute.

Why AEO matters now

When someone asks an AI assistant a question, it answers from the sources it can crawl and parse — and it names them. If AI crawlers are blocked, or your content is an unstructured wall, you’re invisible in exactly the place discovery is moving toward. AEO is how you stay in the answer.

Frequently asked questions

01

What is AEO (Answer Engine Optimization)?

AEO is optimizing your site so AI answer engines — ChatGPT, Claude, Perplexity, Google AI Overviews — can find, understand, and cite your content. It is the AI-era complement to SEO: SEO wins the ranked link, AEO wins the answer.

02

What does an AI-readiness check look at?

This tool checks whether AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot) are allowed to reach your site, whether you publish an llms.txt guide for AI agents, and whether your content is cleanly structured (headings, schema, semantic HTML) so a model can extract and attribute it.

03

What is llms.txt?

llms.txt is an emerging standard — a plain-text file at your site root that gives AI agents a curated map of your most important content, similar to how robots.txt and sitemap.xml guide search crawlers. Publishing one is a low-cost signal that you want to be used well by AI.

04

How is this different from an AI visibility check?

This checks whether your site is technically READY for AI (crawlable, guided, extractable). An AI visibility check asks the next question — whether your brand actually shows up when people ask AI assistants. Get AI-ready first, then measure your visibility.
