What is AI visibility?
AI visibility describes how easily answer engines can find your page, understand it and cite it. Furthermore, ChatGPT, Claude, Perplexity, Gemini and Google AI Overviews all depend on crawlers that fetch pages first. If a crawler cannot reach or read your page, an AI answer cannot quote it.
Most failures are technical and fixable. Moreover, a robots.txt rule blocks a search bot. A security setting rejects unknown user agents. In addition, the main text loads only after JavaScript runs. This checker finds those problems in seconds.
What this AI visibility checker tests
The tool fetches your page from our server, reads the raw HTML like a crawler, and then scores 26 signals in four groups.
Crawler access (38 points)
- The page loads with HTTP 200 over HTTPS
- robots.txt allows OAI-SearchBot, Claude-SearchBot, PerplexityBot, Googlebot and Bingbot
- robots.txt allows user-triggered fetchers such as ChatGPT-User
- The page has no noindex directive
- A sitemap and an llms.txt file exist
Content clarity (30 points)
- Title tag, meta description and one H1
- H2 subheadings and question-style headings
- Readable text in the raw HTML, without JavaScript
- Canonical URL and language declared
- Lists or tables for scannable facts
Structured data (22 points)
- Valid JSON-LD on the page
- Organization, Person or WebSite entity
- Page type, FAQPage and BreadcrumbList markup
- Author and dates inside Article schema
Trust signals (10 points)
- Open Graph title, description and image
- Links to About, Contact, Privacy and policy pages
- Outbound links to sources
The report also lists thirteen AI and search crawlers with their status from your robots.txt. Additionally, training crawlers such as GPTBot and ClaudeBot show as information, because blocking them is a policy choice and does not remove you from AI search.
How to read your score
A score of 85 or more means crawlers can reach and read the page with few obstacles. Furthermore, between 70 and 84, the page works but leaves value on the table. Between 50 and 69, important signals are missing. Moreover, below 50, a crawler probably struggles to use the page.
Start with the Fix these first list. In addition, it ranks problems by the points they cost you. Then work through each group, and run the check again after every change. Additionally, treat the number as a guide. It is our own checklist, not a ranking factor from Google or any AI company.
Training bots, search bots and user bots
AI companies run different crawlers for different jobs. Furthermore, training crawlers, such as GPTBot and ClaudeBot, collect content that may train models. Search crawlers, such as OAI-SearchBot, Claude-SearchBot and PerplexityBot, build the indexes behind AI answers. Moreover, user fetchers, such as ChatGPT-User, open a page when a person asks about it.
Therefore a site can block training and still appear in AI answers. In addition, each crawler needs its own robots.txt rule. OpenAI has said that robots.txt rules may not apply to ChatGPT-User, because a person triggers that fetch. Additionally, see what real crawlers do on real sites in our Crawler Observatory.
Next, run the AI visibility checker, build structured data with the schema markup generator, or browse all free AEO tools. If you want a specialist to do the work, see our AEO services.

Questions
What is an AI visibility checker?
It is a tool that tests whether AI crawlers can reach, read and trust a web page. Furthermore, this one fetches the page, robots.txt, sitemap and llms.txt from our server, then scores 26 signals and lists the fixes in priority order.
Does allowing GPTBot or ClaudeBot make my site appear in AI answers?
Not by itself. Moreover, GPTBot and ClaudeBot are training crawlers. The search crawlers, OAI-SearchBot, Claude-SearchBot and PerplexityBot, build the indexes that power AI answers. In addition, check that those bots are allowed, and treat training bots as a separate decision.
Should I block AI training crawlers?
That is your decision. Additionally, blocking GPTBot, ClaudeBot or Google-Extended limits model training use of your content. It does not stop AI search crawlers from citing you, as long as they remain allowed. Furthermore, the checker reports training bots as information and does not score them.
Why is my score low when my content is good?
Most low scores come from technical gaps. Moreover, common causes are text that loads only through JavaScript, a robots.txt rule that blocks search bots, a firewall that rejects crawlers, a noindex tag, or missing structured data. The fix list shows which one costs you the most points.
More questions
Does the checker run JavaScript?
No. In addition, it reads the raw HTML that your server sends, because many AI crawlers do the same. If your main content appears only after scripts run, the checker will report little readable text. Additionally, that result is a real problem to fix.
Is the AEO score a Google or AI ranking factor?
No. Furthermore, the score is our own checklist of crawler access, content clarity, structured data and trust signals. It shows how easy a page is to reach, read and trust. Moreover, it does not predict rankings or citations.
How often should I check my pages?
Run the checker after any change to robots.txt, your theme, your CDN or firewall rules, or your structured data. Otherwise, check your key pages once a month.
