Free AEO Audit Tool: Check Your AI Visibility
Canonry's free AEO audit scores any page across 16 public factors tied to AI readability, entity clarity, and answer-engine visibility. Paste a URL to see what ChatGPT, Claude, Gemini, and Perplexity can infer from your site today.
How It Works
Four steps from URL to actionable results.
The free audit crawls your site, scores 16 public factors, and queries a live AI model so you can see exactly what answer engines understand about your business today.
Enter your URL
Paste any page URL. We analyze that single page only, not your whole site. This lets you check your homepage, a key landing page, or any page you want AI to understand.
We crawl and analyze 16 factors
Our engine checks structured data, schema validity, entity clarity, content depth, trust signals, snippet eligibility, technical SEO, and 9 other public factors on that page that affect how AI understands it.
An AI model reads your site live
We send your page content to an AI model and ask it to extract the key phrases it can infer about your business, services, location, and credibility.
You get a score, evidence, and fixes
The results show a 0 to 100 score, a signal-by-signal breakdown, the exact phrases AI extracted from your page, and the top 3 actions ranked by impact.
Frequently Asked Questions
Common questions about the AEO audit
What does the free AEO audit check?
The audit scans a single URL and scores it across 16 public AEO factors, including structured data (JSON-LD), schema validity, AI-readable content (llms.txt and llms-full.txt), entity consistency, content depth, citations, content freshness, FAQ schema, snippet eligibility, technical SEO, and AI crawler access. It also sends the page to a live AI model and shows you the exact phrases the model can infer about your business, so you can see what AI engines understand from your site today.
How long does the audit take?
Around 5 to 15 seconds for most pages. We crawl the URL, run all 16 factor analyzers, and ask an AI model to extract what it can infer from the content. You get a 0 to 100 score, a signal-by-signal evidence breakdown, the exact phrases AI extracted from your page, and the top 3 fixes ranked by impact.
Is the AEO audit really free?
Yes. The page-level audit is free within fair-use rate limits of 10 runs per hour per IP. The audit engine is open source as @ainyc/aeo-audit on npm and GitHub, so you can inspect the scoring or run it locally without going through the website. The optional Full AI Visibility Report and execution work are paid services, but the page check itself stays free.
Can I audit any website?
Yes, any public URL with HTML content works. The audit covers a single page at a time, so you can run it on your homepage, a key landing page, or any specific URL you want AI engines to understand. You do not need to be the site owner to run it, which also makes the tool useful for benchmarking competitors.
How does the AEO audit differ from a traditional SEO audit?
A traditional SEO audit grades how a page ranks in Google search results, focusing on signals like backlinks, keyword targeting, and Core Web Vitals. The Canonry AEO audit grades how easily AI answer engines like ChatGPT, Claude, Gemini, and Perplexity can read, trust, and cite the page. It looks at structured data depth, entity consistency, AI-readable files (llms.txt and llms-full.txt), definition-style content blocks, FAQ and HowTo schema, and AI crawler access in robots.txt. The two audits overlap on technical SEO basics but diverge on what counts as a citation-worthy signal.
Which AI engines does the audit cover?
The factor scoring is engine-agnostic and reflects signals that ChatGPT, Claude, Gemini, Copilot, and Perplexity all rely on, including structured data, named entities, content extractability, and citation signals. The live AI extraction step that shows the phrases a model can infer about your business currently runs against Google Gemini with an OpenAI fallback, so the quoted summary represents how a leading frontier model would describe your page based only on what it can read.
Will the audit fix my AEO score automatically?
No. The free AEO audit tool diagnoses the page and shows you exactly which of the 16 factors are failing, but it does not edit your site. After you review the evidence and the top 3 fixes, you can either implement the recommendations yourself, share the report with your developer, or request the Canonry Full AI Visibility Report and done-for-you execution to have the fixes implemented across markup, content, and AI-readable files.
How often should I run the AEO audit?
For most sites, monthly is enough to catch regressions from content updates, schema changes, or new framework releases. Canonry re-audits client sites after every meaningful content or schema change because answer engines re-crawl and re-rank citations frequently. If you publish blog posts or change service descriptions weekly, run the audit on the changed page within a day or two of the change to confirm structured data and entity signals stayed consistent.
