The free AI SEO audit for your website
A regular SEO audit checks whether Google can read your site. This free AI SEO audit checks something newer: whether ChatGPT, Perplexity, Claude, and Google's own AI Overviews can reach it, understand it, and cite it. Most sites that fail have no idea, since the block is rarely deliberate. It is a robots.txt rule inherited from a CDN default, or a firewall that quietly turns away anything that is not a browser. Neither shows up when you look at your own site in Chrome. Run the free AI SEO audit tool below and find out in a few seconds.
What this AI SEO audit actually checks
- AI crawler access: whether OAI-SearchBot, PerplexityBot, ClaudeBot, and Google-Extended are explicitly allowed or accidentally blocked in robots.txt, and whether a WAF is challenging non-browser requests before they ever reach your server.
- Technical foundations: status codes, redirect chains, and whether your content actually loads without depending on client-side JavaScript a crawler may never execute.
- Extractability and structure: whether answers, definitions, and key facts sit in the HTML in a form a retrieval system can lift cleanly, rather than buried under a wall of unstructured text.
- Structured data and entity markup: Organization, Article, Product, and FAQPage schema, checked against what's actually visible on the page rather than assumed from a template.
- Citation readiness: the signals that make a specific page a plausible source for a specific answer, beyond simply being a page that ranks.
- Images and machine metadata: alt text, Open Graph tags, and whether visual content has any text-based fallback a crawler can read at all.
- The agent-facing surface: emerging conventions including MCP discovery, agent cards, security.txt, OpenAPI documentation, content feeds, and Markdown content negotiation, plus commerce markup on sites that sell.
The rest of the 280-check framework is marked for manual review rather than guessed at, and the report explains which items and why. Topical authority requires reading a whole site against a topic map. Off-site evidence requires a backlink index. Most of agent security is internal architecture no external fetch can see from outside. An honest AI SEO audit tool says so instead of inventing a score to fill the gap, since a fabricated authority number is how an audit tool loses the right to be trusted on everything else it reports. Emerging conventions get graded on a different curve too. A site with no MCP server isn't penalized for it, because MCP discovery is still an unratified draft, and marking a site down against a standard that doesn't officially exist yet would mean failing people against a rule nobody agreed to. Presence earns credit. Absence gets reported, not punished.
Add an email and the audit goes further. We crawl a sample of your site and send a branded PDF covering the checks that only make sense across many pages at once, duplicate titles, whether anything on the site is ever dated, whether your own pages link to each other, and whether your markup names your organization consistently from one page to the next.
Why An AI SEO Audit Is Different From A Regular One
A regular SEO audit and an AI SEO audit ask two different questions. Classic tools check whether Googlebot can crawl, index, and rank a page, the same way an ai mode seo analysis tool might score your Core Web Vitals or backlinks. This free AI SEO audit checks whether an entirely different set of non-human visitors, the crawlers behind ChatGPT Search, Perplexity, Claude, and Google's AI Overviews, can do the same thing, since a page can rank on page one of Google and still be functionally invisible to an AI assistant reading robots.txt differently than Googlebot does. Three root causes explain most failures we see when we audit website pages for AI search engine readiness: a robots.txt rule that blocks an AI crawler by name, content that only exists after JavaScript runs, and structured data that's missing, outdated, or contradicts what's actually on the page. This tool checks all three in one pass. If you've compared ai llm seo audits from a few different vendors, the difference usually comes down to how honestly they handle what a single fetch cannot verify. This one tells you.
FAQ
- What does this AI SEO audit actually check?
- Whether AI crawlers such as OAI-SearchBot, PerplexityBot, and ClaudeBot are allowed to reach your site, whether your content lives in the HTML rather than being painted in by JavaScript after load, whether structured data tells assistants what you are, and the technical foundations underneath all of it. It's the automatable subset of our full AI Visibility Audit framework, 280 checks across 18 visibility layers spanning ChatGPT, Claude, Google AI Overviews, Perplexity, and Copilot.
- Is there a free AI SEO audit tool, or does this require a paid plan?
- The audit itself is free with no account and no credit card. Enter a URL and the tool runs the automated checks in seconds. Adding an email opens up a deeper, multi-page crawl and a branded PDF report, but the core AI SEO audit stays free either way.
- How is this different from an AI website rating tool that just gives me a score?
- Most scoring tools guess at everything a single page fetch cannot actually confirm, then present a confident number anyway. This one only scores checks that genuinely ran, shows you how many that was, and marks anything requiring human judgment, like topical authority or off-site evidence, for manual review instead of inventing a figure for it.
- Why would an AI assistant not be able to see my site?
- Two common reasons. Your robots.txt may name AI crawlers and disallow them, often inherited from a CDN default or a blanket "block AI scrapers" toggle nobody reviewed line by line. Or your firewall may be challenging every non-browser request, which blocks assistants without ever appearing in robots.txt and stays invisible from your own browser.
- Do you bypass bot protection to run the audit?
- No, and this matters more than it might seem. We fetch pages the way any compliant commercial crawler would, identifying ourselves honestly in the request rather than disguising it as a browser. If a site refuses that request outright, the audit reports exactly that finding rather than working around it, because a refused fetch is arguably the single most useful thing an AI SEO audit can tell you: the same wall that just stopped us from reaching your content is, in all likelihood, the same wall quietly stopping ChatGPT, Perplexity, and every other AI assistant that has tried and failed before you ever noticed.
- How accurate is the score?
- The score only reflects checks that actually ran, and the tool shows how many of those checks completed alongside the number. If too little of a site could be reached, you get no score rather than a misleading one.
