Does ChatGPT know that your website exists?

Imagine a potential client no longer asking Google, but ChatGPT: "Which agency can optimize my Magento shop?" or "What's the best tool for AI visibility?" The answer includes three or four concrete recommendations – with names. The only question is: Are you one of them?

Traditional search engine optimization (SEO) revolves around Google rankings. But a growing portion of product and service searches now rely on AI assistants like ChatGPT, Perplexity, and the AI ​​Overviews directly within Google Search. These systems draw their results from websites that their AI crawlers are allowed to read . Those who block these crawlers—often unintentionally—simply won't appear in the AI ​​results, regardless of the quality of their content.

This article explains, without hype, what “AI visibility” really means, which three mistakes make you AI invisible, and how you can check your status for free in 30 seconds.

What “AI visibility” really means

AI visibility is not the same as a good Google ranking. It's about the question: Can AI systems retrieve your content and use it in their search results?

The underlying mechanism is simple. AI assistants draw their knowledge from two sources:

1. training data – large amounts of text with which a model was trained only once. Whether your page is included depends on the training time.
2. Live retrieval – when ChatGPT, Perplexity & Co. at the moment of the question Check current websites to verify an answer. This is the lever you can influence today.

For your visibility in current AI responses, point 2 is particularly important: Are your pages being accessed by the right crawlers – and are they prepared in such a way that the AI ​​understands and quotes them?

The two types of AI crawlers – the most important difference

This is where most guides make a mistake: they lump all "AI bots" together. In fact, there are two types , and they have opposing consequences:

• Training crawler collect content for model training (e.g. GPTBot, anthropic-ai, Google-ExtendedBlocking them is a value judgment ("Should my texts be included in the training?") – it costs you no AI visibility in current answers.
• Search/retrieval crawler build the index for AI search or retrieve pages live (e.g. OAI-SearchBot, PerplexityBot, Claude-SearchBot, ChatGPT-UserBlocking them means: They disappear from the AI ​​responses.

The insidious thing is: Many shops reflexively... 2023/2024 GPTBot The robots are blocked in the robots.txt file to "prevent them from being used for AI training." This is legitimate – however, it is often mistakenly interpreted as a blanket ban. aller AI bots. Those who want visibility but not training can separate the two:

# KI-Suche erlauben  Sichtbarkeit in ChatGPT, Perplexity, Claude
User-agent: OAI-SearchBot
Allow: /

User-agent: PerplexityBot
Allow: /

User-agent: Claude-SearchBot
Allow: /

# Training (optional) ausschliessen  ohne die KI-Suche zu verlieren
User-agent: GPTBot
Disallow: /

User-agent: anthropic-ai
Disallow: /

User-agent: Google-Extended
Disallow: /

An overview of the most important AI crawlers:

Important information regarding Google Extended: It solely controls whether your content is included in Gemini training. Blocking it will not affect your Google ranking or your chances of receiving AI Overviews. These are handled through the normal process. Googlebot.

Google AI Overviews is a special case.

You don't need a special setup for Google's AI-powered search results. Google clarified this in a dedicated guide in 2026: "Optimizing for generative AI search is still optimization for search – so SEO is still the same."

Specifically, this means:

• AI Overviews draw their information from the normal Google index. If Googlebot If your pages can be crawled and rendered, and you are eligible for snippets, you may also appear in the AI ​​overviews.
• Google explicitly states: llms.txt, AI-specific rewriting, "content chunking" or special markup are not necessary. You don't need to generate anything extra that's machine-readable.
• What counts is the same as with good SEO: crawlable, renderable pages, clean robots.txt, good page experience – and above all independent, experience-based content instead of generic summaries.

In other words, the "AI bot problem" primarily affects standalone assistants (ChatGPT, Perplexity, Claude). For Google AI reviews, it's classic, clean SEO.

3 things that make your website AI-invisible

1. Your robots.txt file is blocking the wrong bots.

Blanket blocks (User-agent: * with too wide DisallowOutdated "block AI" snippets or overly aggressive bot protection (WAF/Cloudflare rules, security plugins) often block the very search crawlers you actually want. The result: they disappear from AI responses without you even realizing it.

2. Their content is inaccessible or incomprehensible.

If core content is only loaded via JavaScript, hidden behind logins, or presented as a thin, generic wall of text, AI systems cannot properly understand or cite it. Crawlability and renderable, standalone HTML are essential.

3. Clear, quotable answers are lacking.

AI systems prefer to cite pages that answer a question directly and precisely. Lengthy advertising copy without clear statements is used less often as evidence than a concise paragraph that addresses the question exactly.

llms.txt – what's true and what's not

There was a lot of fuss surrounding the llms.txt file in 2026. Here's an honest assessment – ​​which you won't find in most articles:

• What is it: a simple Markdown file under /llms.txt, which gives AI systems a curated overview of your most important content. A Community Convention, (still) no official standard.
• What it is not: a ranking lever. Google explicitly does not support llms.txt. and isn't planning to either. Analysis Of approximately 300.000 domains, only about 10% have been adopted, and direct access by AI crawlers is still negligible.
• Where it makes a difference: Anthropic and Perplexity Referencing llms.txt; well-maintained files can easily increase the citation frequency there. Above all, it makes use of Developer and agent tools (Cursor, Windsurf, Claude Code, GitHub Copilot, etc.) very active.
• And finally ... llms.txt is inexpensive to create and doesn't cause any harm – but Consider it a bonus, not a miracle cureThe requirement is a clean robots.txt file for search crawlers and crawlable, high-quality content.

Your AI Visibility Checklist

1. Check robots.txt: Sind OAI-SearchBot, PerplexityBot, Claude-SearchBot & the normal Googlebot allowed?
2. Check bot protection: Is your WAF/security plugin accidentally blocking AI search crawlers?
3. Make conscious decisions about training: GPTBot/anthropic-ai/Google-Extended Allowing or blocking – a value judgment, not a visibility issue.
4. Crawlability & Rendering: Is your core content accessible without JavaScript hurdles and without a login?
5. Citable content: Do you answer real questions clearly and independently (instead of generic texts)?
6. Freestyle: Create llms.txt – pragmatically, without exaggeration.
7. Measure: Ask ChatGPT/Perplexity about your topic every few weeks – are you mentioned?
