What is Answer Engine Optimization (AEO)?

AEO is the practice of optimizing your content to be cited by AI assistants like ChatGPT, Perplexity, Claude, and other generative AI systems. Unlike traditional SEO which targets search engines, AEO focuses on making your content easily extractable by AI.

The 6 Critical AEO Checks

  • 1. AI Crawler Access (20 pts): Ensures GPTBot, ClaudeBot, PerplexityBot can access your site via robots.txt
  • 2. llms.txt (15 pts): Validates presence of llms.txt file with sitemap and use case references
  • 3. Structured Data (25 pts): Checks for JSON-LD schemas (WebSite, Person, BlogPosting, FAQPage)
  • 4. Extractability (20 pts): Analyzes semantic HTML, heading hierarchy, and text-to-HTML ratio
  • 5. AI Metadata (10 pts): Verifies canonical URLs, OpenGraph tags, and meta descriptions
  • 6. Answer Format (10 pts): Checks for FAQ/HowTo schemas, lists, tables, and proper heading structure

FAQ

What is an AEO audit?

An AEO (Answer Engine Optimization) audit checks whether AI systems like ChatGPT, Perplexity, and Claude can access, extract, and cite your website. This tool runs 6 automated checks against your domain and returns a scored report in about 60 seconds.

How is AEO different from SEO?

SEO optimizes for ranking in traditional search results using backlinks and domain authority. AEO optimizes for extraction: whether AI systems can pull accurate, citable content from your pages. A site can rank well on Google and still be invisible to AI answer engines.

What does this AEO audit tool check?

Six things: AI crawler access via robots.txt (GPTBot, ClaudeBot, PerplexityBot, YouBot), llms.txt presence and content, structured data (WebSite, Person, BlogPosting, FAQPage, HowTo schema), content extractability (semantic HTML, heading count, text-to-HTML ratio, image alt text), AI metadata (canonical URL, OpenGraph tags, meta description), and answer-ready formatting (FAQ/HowTo schema, lists, tables, heading structure).

Is this AEO audit tool free?

Yes. Enter any domain and get a full 6-check score with no signup. For a deeper audit that tests which of your specific URLs AI engines actually cite, see the paid citability.dev citation audit.
