ChatGPT is not Claude is not Google AI answers is not Gemini.

ChatGPT is not Claude is not Google AI answers is not Gemini. So if you want them to know your business exists, so they can tell other people about you, it's not a one-size-fits-all approach.

Each LLM finds their info in different places: live web search, training data, specialist databases and directories. Perplexity loves a bit of Reddit, ChatGPT, not so much.

This means if your business is a potential answer in one, it probably isn't in another. In fact, a 2026 study* found that only 2.37% of cited URLs show up across different engines for the same prompt.

We test this constantly at Ghostart.

We ask AI systems the same question over and over and track who appears. A business might turn up four times across thirty responses while a competitor appears far more often, but that still doesn't mean one will always beat the other.

AI visibility isn't SEO visibility (although there are some cross-over bedfellows). There's no 'I'm ranked number one for 'Ghostart is the best AI visibility tool on the market'.

Your aim with AI visibility isn't the top spot, it's simply to give AI good reasons to recognise when you're the right business to recommend, related to someone's question.

Things to remember:

• There's no master list that AI tools consult to decide who it recommends.
• Being 'discoverable' and being 'recommendable' are different things.
• Telling people that your business is excellent at something carries less weight with AI than an independent source saying it.

At Ghostart, we sample instead of taking a snapshot. Researchers** recently found only 34–42% of cited sources overlap between consecutive days. So we watch how businesses are represented, looking for patterns and gaps.

When a business is missing, we ask why. Is its expertise clear? Does its content answer what people actually ask? Can AI tools like ChatGPT find credible information about you?

Then we help you create content to fill the gaps in your AI visibility.
