Free AEO Audit Tool

Instant Answer Engine Optimization checker for ChatGPT, Perplexity, and Claude. Get scored across 6 critical AEO checks in 60 seconds, no signup required.

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.

What Counts Toward the Score

  • 1. AI Crawler Access (20 pts): Ensures GPTBot, ClaudeBot, PerplexityBot and YouBot are not blocked in robots.txt
  • 2. Extractability (20 pts): Analyzes semantic HTML, heading hierarchy, and text-to-HTML ratio
  • 3. AI Metadata (10 pts): Verifies canonical URLs, OpenGraph tags, and meta descriptions
  • 4. Answer Format (10 pts): Checks for lists, tables, and heading density

The score is the share of those 60 points your page earns. Three more items are reported but not scored. Structured data (JSON-LD) helps search results, but a controlled test of 1,885 pages found it did not change AI citations. llms.txt is optional: AI crawlers almost never request it. Off-site mentions of your brand track AI visibility most closely, and a one-page check cannot see them.

This tool checks your infrastructure. For a full AI visibility scan of your domain, including which AI engines actually cite your URLs, run the free AI Visibility Checker. If you run a local business and want the fixes done for you, start with the free Fowned audit.

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 automated checks against your domain and returns a scored report in a few 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?

Four scored checks: AI crawler access via robots.txt (GPTBot, ClaudeBot, PerplexityBot, YouBot), 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 (lists, tables, heading structure). It also reports structured data and llms.txt without scoring them, because controlled tests found neither changes how often AI systems cite a page. Off-site mentions of your brand matter most, and a one-page check cannot see them, so the report marks that as not measured.

Is this AEO audit tool free?

Yes. Enter any domain and get a full score with no signup. To see which of your URLs AI engines actually cite, run the free citability.dev scan. Paid Monitoring on the same site tracks how that changes week to week.
