Why you appear on Google but not on ChatGPT (and what that says about your website)

It’s a situation happening more and more. A business owner opens ChatGPT, types “best [their service] in [their city]”, and the answer names three or four competitors. Not them. And yet, if they open Google and search the same thing, their website shows up in the top results.

How can you appear on Google and not on ChatGPT? The short answer: because they’re two different ways of reading the web, and a website can be perfectly optimised for one and almost invisible to the other.

Google reads you as a search engine. AI reads you as a journalist.

Google crawls, indexes, and when someone asks, it ranks results by relevance and authority. Its job is to give you links so you decide.

ChatGPT, Perplexity or Google AI Overviews do something different: they read several websites, summarise what they say and write an answer signed by them. To write that answer they need a website that’s easy to cite: clear information, verifiable data and answers that can be extracted without being misread.

A website can have great content, strong rankings and good backlinks, and still not fit as a citable source. It’s not broken: it’s optimised for something else.

The five most common reasons

When a website meets the classic SEO checklist but still doesn’t appear cited in AI answers, it almost always comes down to one of these five reasons.

Your website doesn’t tell the machine who you are. There’s an information layer, invisible to the user, that AIs read before the text. A kind of technical fact-sheet that says “this is a business, called X, located in Y, offers Z”. Without that sheet, the AI has to guess by reading scattered paragraphs, and often decides not to risk citing you. This layer isn’t added from the editor: it’s set up by whoever builds the website, and many templates ship it broken or incomplete.

Your information isn’t consistent across sources. AI cross-references data: your website, your Google profile, your Instagram, the directories you appear in. If your website says “3 Main St”, Google says “Main Street 3” and a directory says “main street number 3”, to a person it’s the same; to an AI it’s three conflicting facts. When in doubt, it doesn’t cite you.

Your content doesn’t answer literal questions. If someone asks “how much does a plumber cost on a Sunday in Las Palmas?” and your website talks about “competitive rates” in the abstract, AI has nothing to extract. The websites that get cited usually have the exact question as a heading and the answer right below, no detours.

Your website is slow or has technical errors. The bots feeding these models crawl thousands of pages a day. When one is slow to load or returns intermittent errors, they mark that source as unreliable and prefer another. Speed and technical solidity aren’t just SEO anymore: they’re a requirement for an AI to trust what it reads.

Your information looks AI-generated. Sounds paradoxical, but it happens. If your content is flat text with no personality, vague data and template-generated phrases, the models detect that pattern and lower your priority as a source. AI prefers citing humans to citing other AIs.

”But my SEO has been solid for years”

Classic SEO still matters, a lot. AI doesn’t invent sources: it cites websites that already rank well. If you don’t show up on Google, you won’t show up on ChatGPT either.

What changes is what comes after. Among five equally well-ranked websites, AI picks the one that makes its job easy: the one with information structured in a machine-readable way, the one that says things clearly and the one that doesn’t contradict its other public sources.

This means older websites with high authority can lose visibility against newer but better-prepared ones. It’s not a prediction: it’s already happening.

What almost no one will tell you

Some things you’ll see repeated online that don’t solve anything (or make it worse):

• Adding phrases like “as per ChatGPT” or “this website complies with GEO” in the footer. No effect at all. AI doesn’t read declarations of intent, it reads data.
• Asking ChatGPT to cite you. The models don’t remember instructions between conversations and don’t pick sources by preference: they pick by structure and reliability.
• Rewriting all your content with AI “optimised for AI”. That’s the fastest way to tank your rankings. Models detect generated text and distrust it.
• Creating a page for every search variation. Penalised in both classic SEO and GEO. Fewer pages, more complete, always.

How to know where to start

The honest answer: you can’t tell at a glance. The five reasons above overlap, and figuring out which weighs most for each website means looking at the technical layer, content, source consistency and performance. A surface review isn’t enough.

What you can do in five minutes: open ChatGPT, ask about your sector in your area, and see who gets cited. If you do, great, your website is doing something right. If not, write down which websites show up and compare with yours: what do they have that you don’t? Often the difference is visible, even if fixing it takes a technical hand.
