What This Checker Can — and Can’t — Tell You
This is an AI visibility readiness audit based on publicly observable website signals. Readiness and actual recommendation are different things: a site can be well-prepared and still never be cited, and the outcome is not something any external tool can measure.
What it can check
Publicly observable website signals such as:
- Crawlability
- robots.txt
- sitemap.xml
- llms.txt presence
- Structured data
- Organization / entity clarity
- Content structure
- AI crawler accessibility signals
What it cannot determine
This tool cannot directly tell you:
- Whether ChatGPT has indexed the site
- Whether OpenAI has stored or trained on the site
- Whether ChatGPT will recommend the business
- Whether the site will be cited in an AI answer
Can ChatGPT See My Website?
It sounds like one question, but it’s really several separate ones:
- Is the website publicly accessible?
- Are relevant crawlers allowed?
- Can machines understand what the business or site is about?
- Is useful content available in crawlable HTML?
- Will an AI system actually choose to use or cite it?
The first four can be partially audited from public website signals — that’s what this checker does. The final outcome cannot be guaranteed by anyone, because it depends on factors outside a website’s control.
What the ChatGPT Website Visibility Checker Tests
The audit evaluates 22 signals across five categories, scored by the same engine embedded at the top of this page.
Technical
5 checksFoundational setup that determines whether a page can be fetched and parsed cleanly.
- HTTPS — the page is served over an encrypted connection.
- Page title — a <title> tag exists and is a sensible length (roughly 15–65 characters).
- Meta description — a description is present and around 50–160 characters.
- Canonical tag — a rel="canonical" link is present so URL variants aren't treated as separate pages.
- OpenGraph tags — og:title, og:description, and og:image are all present.
Entity / Brand Clarity
4 checksSignals that let a machine tie the page to a single, identifiable organization.
- Identifiable brand name — a name is clearly declared (ideally via og:site_name), not just guessed from the domain.
- About page — the homepage links to an About, Company, Who We Are, Our Story, Leadership, or Mission/Values page.
- Contact information — a direct mailto: or tel: link is present.
- Author information — checked only on article/blog-style pages; marked not applicable elsewhere.
Content
5 checksWhether there is enough clear, crawlable text for a system to extract meaning from.
- H1 heading — exactly one H1 describes the page's main topic.
- Heading structure — headings form a clean H1 → H2 → H3 hierarchy.
- Content length — the main content has real depth (around 600+ words scores full marks).
- Internal links — the page links to enough of its own pages (roughly 10+) to convey site structure.
- Semantic clarity — content is organized into several substantial paragraphs rather than fragments.
Structured Data
5 checksMachine-readable schema.org markup that labels what the page and entity actually are.
- Structured data present — any schema.org JSON-LD or microdata was found.
- Organization schema — an Organization (or LocalBusiness / Corporation) type is declared.
- WebSite schema — a WebSite type is declared.
- Article schema — checked when the page looks like article/blog content; not applicable otherwise.
- FAQ schema — checked when FAQ-style Q&A content is detected on the page.
AI Crawler Readiness
3 checksPublicly fetched files that affect whether crawlers can reach and map the site.
- robots.txt — a robots.txt exists at the domain root and does not block known AI crawler user-agents.
- sitemap.xml — a valid sitemap.xml is reachable at the site root.
- llms.txt — an llms.txt file is present (an emerging convention, treated as a nice-to-have).
Each check returns pass, warning, or fail with a plain-language explanation, plus an overall readiness score and a short list of what to fix first. Some checks (author information, Article schema, FAQ schema) are marked not applicable when the page type doesn’t call for them. For a JSON-LD-only view of a single page — every Schema.org type, parse errors, and per-type properties — use the AI Schema Markup Checker.
Common Reasons a Website May Be Hard for AI Systems to Understand
1Blocked or restrictive crawler rules
A blanket "Disallow: /" in robots.txt, rules that target specific AI crawler user-agents, or bot-protection tools that challenge every non-browser request can all stop a crawler before it reads a single page.
Why it matters: If a crawler can't fetch the page, nothing else on it matters — the content is never seen in the first place.
Practical fix: Review robots.txt and any CDN or firewall bot rules, and explicitly allow the AI crawler user-agents you're comfortable with.
2Missing or broken sitemap
A sitemap.xml that returns a 404, isn't valid XML, or is referenced in robots.txt but unreachable gives crawlers no map of which URLs exist.
Why it matters: A sitemap helps crawlers discover pages they might not reach through links alone, and confirms which URLs you consider canonical.
Practical fix: Publish a valid sitemap.xml at your domain root, keep it current, and reference it with a Sitemap: line in robots.txt.
3Unclear organization or brand identity
If your name isn't stated consistently in the title tag, og:site_name, visible text, and structured data, a machine has to guess the "who" from the domain.
Why it matters: Systems tend to favor sources they can confidently attribute to a real, named entity over pages where the identity is ambiguous.
Practical fix: Declare your exact brand name in og:site_name and Organization schema, and use it consistently across the site.
4Weak structured data
No JSON-LD, or only generic markup, leaves systems to infer your entity and content type from unstructured text.
Why it matters: Organization, WebSite, and Article/FAQ schema are among the least ambiguous signals available for understanding a page.
Practical fix: Add JSON-LD to your key pages, starting with Organization and WebSite schema on the homepage.
5Important information hidden in hard-to-crawl formats
Text baked into images, locked inside sliders, or rendered only by client-side JavaScript may not be present in the HTML a crawler receives.
Why it matters: A crawler generally works from the returned HTML; content it can't see as text is content it can't use.
Practical fix: Keep the substance of each page in plain, server-rendered HTML, and use images for illustration rather than for conveying key facts.
6Thin or vague content
Very short pages or purely promotional copy give a system little concrete material to work with.
Why it matters: Systems tend to draw from pages that clearly and specifically address a topic; there's little to extract from a few marketing lines.
Practical fix: Write genuine, specific paragraphs with real depth on the pages that matter most.
7Missing About / company information
No About page — or a page with no real detail about who runs the site and what they do — makes credibility hard to establish.
Why it matters: About-style pages are one of the fastest ways for both machines and people to confirm a source is legitimate.
Practical fix: Publish a clear About (or Company / Our Story) page and link to it from your main navigation or footer.
8Pages that don't answer specific questions clearly
Content organized around slogans or feature lists rather than the questions people actually ask is harder to map to a query.
Why it matters: Direct, well-structured answers are easier to quote usefully than vague or purely promotional copy.
Practical fix: Use descriptive headings phrased around real questions, and answer each one plainly in the paragraph that follows.
Does robots.txt Block ChatGPT?
robots.txt can affect crawler access. It’s usually the first file a crawler requests, and a rule that disallows a specific user-agent — or a blanket Disallow: / under User-agent: * — can keep a crawler from reading the site.
That said, one robots.txt line doesn’t determine all “ChatGPT visibility.” Different AI providers and products may use different crawling and retrieval systems, honor different directives, and change their policies over time. This audit reports what your robots.txt currently says about known AI crawler user-agents; it doesn’t claim to model every provider’s behavior.
OpenAI in particular uses several distinct crawlers — OAI-SearchBot for ChatGPT Search discovery, GPTBot for training, and ChatGPT-User for user-initiated fetches. To see exactly which of them your robots.txt allows or blocks, use the AI Crawler Robots.txt Checker.

Do I Need llms.txt?
- llms.txt is an emerging convention, not an established standard.
- It is not universally required, and most sites don't have one yet.
- Its absence does not mean a website is invisible to AI systems.
- Adding one can provide machine-readable guidance, but it is not a guaranteed ranking or citation factor and shouldn't be presented as one.
The audit flags a missing llms.txt as a low-priority warning rather than a failure, for exactly these reasons.
How to Make Your Website Easier for AI Systems to Understand
- Keep important pages crawlable — avoid blocking them in robots.txt or behind scripts a crawler can't execute.
- Maintain a valid sitemap.xml at your domain root and keep it in sync with your real URLs.
- Review robots.txt so it doesn't unintentionally block AI crawler user-agents or everything under User-agent: *.
- Clearly state your organization or business information, with a consistent name everywhere it appears.
- Maintain an About page that explains who you are, what you do, and why you're credible.
- Use appropriate structured data — Organization and WebSite schema on the homepage, Article/FAQ schema where relevant.
- Answer the real questions your audience asks, in genuine paragraphs rather than images or marketing lines.
- Use descriptive headings that reflect the content beneath them.
- Keep important content in HTML rather than locked inside JavaScript-only widgets or images.
- Keep brand and entity information consistent across the title tag, og:site_name, visible text, and schema.
Access is only half of it — the wording and layout of each page decide whether an AI answer engine can lift a clear answer from it. Run the AEO content readiness check on a specific URL to see how extractable its content is.

Analyze My Website FreeFrequently asked questions
Can ChatGPT see my website?
"Seeing" a website is really several separate things: whether the site is publicly reachable, whether crawlers are permitted, whether a machine can understand what the site is about, whether useful content is in crawlable HTML, and whether an AI system then chooses to use it. The first four can be partially assessed from public website signals. The last one can't be guaranteed or measured by any external tool.
How do I check whether ChatGPT can access my website?
You can review the signals that affect crawler access — robots.txt rules, whether the site loads over HTTPS without a login wall, whether a valid sitemap.xml exists, and whether important content is present in the HTML. This page's audit checks those publicly observable signals. It does not send OpenAI's live crawler to your site or confirm what any provider has actually fetched.
Does this tool check ChatGPT directly?
No. It does not query ChatGPT, OpenAI, or any AI model, and it cannot determine whether a site has been indexed, stored, trained on, cited, or recommended. It is a readiness audit based on publicly observable website signals.
Can robots.txt block AI crawlers?
It can. robots.txt is typically the first file a crawler checks, and rules that disallow a crawler's user-agent — or a blanket Disallow: / under User-agent: * — can prevent it from reading the site. Different AI providers and products may use different crawlers and honor different rules, so one setting does not control every system.
Do I need llms.txt for ChatGPT?
No. llms.txt is an emerging convention, not a universal requirement, and its absence does not make a site invisible to AI systems. Adding one can provide a machine-readable summary, but it should not be treated as a guaranteed ranking or citation factor.
Does Schema markup help AI systems understand a website?
Structured data (schema.org JSON-LD) gives systems an explicit, machine-readable description of your entity and content instead of leaving them to infer it from text. It is one of the clearer signals this audit checks for, but it is one input among many, not a guarantee of any outcome.
Will passing this audit make ChatGPT recommend my website?
No. Passing the audit means your site shows strong readiness signals. Whether any AI system discovers, cites, or recommends a site depends on many factors outside a website's control and outside what this — or any — audit can see or promise.
