In depth

Why a single test tells you nothing

Large language models answer probabilistically: the same question gives you different brands today than tomorrow. A one-off self-test in ChatGPT is therefore not a measurement but a snapshot. LLM monitoring sends defined prompts repeatedly and automatically to several AI systems and aggregates the answers into solid values – only then do trends, effects of GEO measures and competitor movements become visible.

What good LLM monitoring covers

Four dimensions count: mention (does the brand appear?), position (first or tenth?), sentiment (positive, neutral, critical?) and citation (is your own website linked as a source?). On top of that comes the competitor comparison via the Share of Voice. GeoStars measures these values daily across ChatGPT, Google AI Overviews, Gemini, Perplexity and Microsoft Copilot – in one dashboard instead of five separate tools.

Frequently asked questions
For the start, 15–30 buying-decision prompts from your target group are enough. Relevance matters more than volume – plus daily repetition for statistically solid values.
Technically possible (query APIs, parse answers), but a lot of work: real web interfaces instead of API answers, sentiment classification, deduplication of brand mentions and runs across five platforms, three of them daily, usually make a ready-made tool the better choice.
