Free AEO & GEO Audit Tool — Real AI Visibility Data for Your Website
Our free AEO and GEO audit tool checks 23 real signals that determine whether AI engines like ChatGPT, Claude, Perplexity, and Google AI Overviews will cite your site as a trusted source. Unlike traditional SEO audits that focus on keyword rankings, this tool analyzes the exact factors that generative AI systems use to decide whether to include your content in their answers. Every result is fetched live from your actual page — no mock data, no cached results.
What is AEO (Answer Engine Optimization)?
Answer Engine Optimization (AEO) is the practice of structuring your content so AI-powered answer engines can extract, cite, and attribute your brand as a trusted source. Where traditional SEO focused on appearing in a list of blue links, AEO focuses on being the answer itself — the content that ChatGPT quotes, that Perplexity cites, and that Google's AI Overviews surface. The key technical signals include FAQ schema markup (FAQPage JSON-LD), question-format headings (H2s and H3s that end with a question mark), structured lists and tables that AI can extract, author and publication date signals for E-E-A-T, and modular answer-first content blocks of 75–300 words each.
What is GEO (Generative Engine Optimization)?
Generative Engine Optimization (GEO) extends AEO to cover the technical infrastructure that allows AI crawlers to access and index your content. If GPTBot, ClaudeBot, or PerplexityBot are blocked in your robots.txt, no amount of content optimization will help — the AI simply cannot read your site. GEO also covers entity signals: Organization schema that defines your brand identity in the knowledge graph, consistent NAP (Name, Address, Phone) data across the web, author bylines linked to credible profiles, and an About page that establishes your brand's mission and expertise. AI systems cross-reference these entity signals to build confidence in your brand before citing it.
Schema Markup — The Most Impactful AEO Signal
Of all the AEO checks this tool runs, missing FAQPage schema is the highest-impact issue for most sites. FAQPage JSON-LD feeds question-and-answer pairs directly into AI systems and Google's featured snippets. Article schema establishes authorship and publication signals. HowTo schema structures instructional content for AI extraction. Organization schema with sameAs links (pointing to your LinkedIn, Twitter/X, Crunchbase, and Wikipedia entries) builds your entity in AI knowledge graphs. Our tool detects all schema types present on your page and identifies which high-value types are missing.
AI Bot Permissions — Why robots.txt Blocks Kill Your AI Visibility
Many sites that blocked common crawlers years ago are now accidentally blocking AI systems. CCBot (used to build Common Crawl, which trains many LLMs), GPTBot (OpenAI's crawler for ChatGPT), ClaudeBot (Anthropic's crawler), PerplexityBot, and Google-Extended (used for Gemini and AI Overviews) all respect robots.txt. A single "Disallow: /" under "User-agent: *" blocks every AI crawler at once. Our tool fetches your live robots.txt and checks each AI bot individually, showing which are allowed, blocked, or not explicitly mentioned. Not-mentioned bots typically follow the wildcard rule.
The AI Visibility Test — Does Claude Actually Know Your Brand?
The AI Visibility tab goes beyond technical checks — it actually queries the Claude API with three prompts about your brand and reports whether Claude recognizes it and what it says. This gives you a real baseline: before any optimization, does a leading AI model know your brand exists? After optimization work (publishing original research, earning high-authority citations, adding Organization schema with sameAs links, allowing all AI crawlers), you can re-run the test to measure improvement. The test uses Claude Haiku 4.5 and costs approximately $0.0023 per check — roughly $0.07 for a month of daily tests.
AEO vs GEO Signal Summary
| Signal | AEO Impact | GEO Impact |
|---|---|---|
| FAQPage Schema | Very High | Low |
| Question-format H2/H3 headings | High | Low |
| Author markup (E-E-A-T) | High | Medium |
| GPTBot allowed in robots.txt | Low | Very High |
| Organization schema + sameAs | Medium | Very High |
| XML Sitemap | Low | High |
| Lists & structured content | High | Low |
| HTTPS + Canonical URL | Medium | Medium |
How Often Should You Run an AEO & GEO Audit?
Run an audit after every major content publish, after any robots.txt change, after adding or removing schema markup, and after any site migration. AI systems like ChatGPT update their knowledge on a rolling crawl basis — improvements you make today can appear in AI responses within weeks. For most sites, a monthly audit establishes a baseline and tracks progress. Pay particular attention to your AI Visibility score over time: as you earn more high-authority citations, add Organization schema with social sameAs links, and allow all AI crawlers, you should see the score improve from "unknown" toward "known."
