Free AI SEO Audit Tool by Austin Heaton
Austin Heaton’s free AI SEO audit tool checks whether ChatGPT, Perplexity, Claude, and Gemini can crawl, read, and cite your website — then grades your content engine, entity citations, and AI visibility, and estimates the revenue you’re leaving on the table. No email. No signup.
These are the same checks Austin Heaton runs first on every paid AEO audit, running live in your browser against your real site files.
AI visibility score
What is your AI invisibility costing you?
Buyers shortlist vendors inside ChatGPT, Perplexity, and Gemini before they ever talk to sales. Every gap above is an answer where a competitor gets recommended instead of you. Adjust the two assumptions to your business:
Live AI-engine testing — the half this tool can’t automate
Answer engines decide who to recommend from third-party sources and live prompt behavior. Testing that requires running your buyers’ real prompts across the engines and researching your citation footprint — Austin Heaton does it by hand in the full audit:
- The 4-prompt money table — who wins your buyers’ actual AI prompts today
- Listicle & “alternatives” page presence vs. your competitors
- Brand-mention graph and AI citation share across ChatGPT, Perplexity, Gemini & Claude
- A defensible revenue-leakage model and 90-day action plan
Want the citations, not just the checklist?

Austin Heaton built this tool to mirror the first pass of his paid AEO audits: technical access, on-site content, and entity-citation readiness — the three layers that decide whether AI engines can find, understand, and recommend you.
- AI crawler access — does robots.txt block GPTBot (ChatGPT), ClaudeBot (Claude), PerplexityBot, or Google-Extended (Gemini)?
- llms.txt & XML sitemaps — the maps that tell LLMs what to crawl and cite
- Structured data (JSON-LD) — schema markup that makes your entity machine-readable
- Title, meta, H1, canonical & Open Graph — clean, extractable on-page signals
- Content engine — blog volume, plus the BOFU pages AI actually cites: comparisons, “vs” and “alternatives” pages, pricing, case studies
- Answer-shaped content — definitional and how-to pages that map to buyer prompts
- Entity citations — Wikipedia entity presence, schema entity types, sameAs graph, brand consistency
- Missed revenue — a directional estimate of what your visibility gap costs per year
Scored below an A? Every point is recoverable — Austin Heaton fixes these gaps for a living.

Free AI SEO Audit Tool — FAQ
What is an AI SEO audit?
An AI SEO audit (also called an AEO, GEO, or LLM SEO audit) checks whether answer engines — ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews — can crawl your site, understand your entity, and cite you in their answers. Austin Heaton’s audits cover technical access (robots.txt, llms.txt, sitemaps, schema), on-site content, and off-site authority signals like brand mentions and listicle presence.
How does Austin Heaton’s free AI SEO audit tool work?
The tool runs entirely in your browser. It fetches your homepage, robots.txt, llms.txt, and XML sitemaps, analyzes your content mix, and checks your entity footprint — then scores 25+ checks across five categories: technical AEO, AI crawler access, AEO discoverability, on-site content engine, and citations & entity visibility. You also get a directional missed-revenue estimate. About 30 seconds, no email, no signup.
Is this AI SEO audit tool really free?
Yes — completely free, no email required. Austin Heaton offers this layer free because it’s instantly checkable. The full AEO audit — live prompt testing, brand mentions, AI citation share, and a defensible revenue-leakage model — is a manual engagement. Book a call with Austin to get one.
How do I get my website cited by ChatGPT and Perplexity?
Three layers, in Austin Heaton’s framework: first, technical access — let GPTBot, ClaudeBot, and PerplexityBot crawl you, publish llms.txt and clean schema. Second, answer-shaped content — comparison pages, pricing explainers, and definitional posts that map to buyer prompts. Third, off-site authority — get listed on the listicles and “alternatives” pages AI engines already cite. This free tool grades the first two layers instantly.
How is the missed-revenue estimate calculated?
It’s directional, with every assumption stated: your inbound customers per month, times twelve, times the share of B2B buyers who use AI tools in vendor research (estimated at ~60%), times your visibility gap (100 minus your score), times your average deal value — shown as a range. It’s a conversation starter, not a forecast. Austin Heaton builds a defensible, category-specific leakage model in the full audit.
What’s the difference between this free check and Austin Heaton’s full AEO audit?
The free tool covers what a browser can verify: crawler access, llms.txt, sitemaps, schema, content mix, and entity signals. Austin Heaton’s full audit adds the parts that need human research — testing your buyers’ actual prompts across ChatGPT, Perplexity, Gemini, and Claude; mapping which competitors win each answer; your brand-mention graph; and a revenue-leakage model with a 90-day action plan.
