You ask ChatGPT a question your business should own, and it recommends three competitors. You are not mentioned at all. It is a strange feeling, and it is becoming a common one.
The good news is that this is rarely a mystery. When a site is missing from AI answers it is almost always for one of five reasons, and you can check every one of them yourself.
1. The crawlers cannot get in
AI companies read the web with their own crawlers. OpenAI runs GPTBot and OAI-SearchBot, Perplexity runs PerplexityBot, and Anthropic runs ClaudeBot. Many sites block them without meaning to, through a robots.txt rule copied from a template or a firewall setting that turns away anything that is not a browser.
Open your robots.txt file and look for those names. Then check your CDN or security plugin for bot rules. If the crawler is refused at the door, nothing else on this list matters.
2. The content is not in the HTML
Most AI crawlers do not run JavaScript. If a page arrives as an empty shell and fills itself in afterwards, a person sees a full page and a crawler sees almost nothing. View the page source, not the rendered page, and search it for a sentence from your main content. If the sentence is missing, that page is hard for an AI crawler to read.
3. Search engines do not rank you for it
When an assistant searches the web to build an answer, it leans on search indexes: Bing among them in the case of ChatGPT, and Google for Gemini and AI Overviews. A page that is not indexed, or that sits on page five, is unlikely to be pulled in. Ordinary SEO is still the entry ticket.
4. The page never actually answers
Engines quote the sentence that resolves the question. If your answer is buried under a long introduction, or spread thinly across a page of marketing copy, there is nothing clean to lift. Put the answer in the first sentence under a clear heading, and let each section make sense on its own.
5. Nobody else mentions you
Assistants do not take your word for it. They weigh what review sites, directories, trade publications and forums such as Reddit say about you. A business that exists only on its own website looks unproven. This is the slowest of the five to fix, and often the one that matters most.
Check it yourself in an afternoon
- Read robots.txtLook for GPTBot, OAI-SearchBot, PerplexityBot and ClaudeBot, and for any rule that blocks everything.
- View the sourceSearch the raw HTML of your key pages for a sentence a customer would need to read.
- Ask the questionsPut your ten most valuable customer questions to each assistant and write down who gets named.
Being invisible to AI is rarely about AI. It is usually an old problem of access, clarity or reputation showing up in a new place.
You may have heard of llms.txt, a plain file that points AI systems to your most useful pages. It is a sensible thing to publish and takes a few minutes, but it is a convention, not a switch. It will not rescue a site with the problems above.
Nalza watches all five for you: crawler access, rendering, rankings, how quotable each page is, and how often each engine actually names you. To see where your site stands today, the free audit takes about a minute.
