Measuring LLM Visibility — Track Your Brand in ChatGPT, Perplexity and Claude
SHORT ANSWER
AI visibility means your business is mentioned and recommended when potential customers ask relevant questions to ChatGPT, Gemini, Copilot, Claude and Perplexity. GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) are the methodologies that secure this visibility. Periscopify measures your AI visibility and delivers a prioritised action plan to improve it.
What is LLM visibility measurement?
LLM visibility measurement is the practice of tracking how often and how positively your business is mentioned and recommended in answers from LLMs like ChatGPT, Perplexity, Claude, Gemini, Copilot and Google AI Overviews. When a potential customer asks AI who delivers what you offer — are you visible or invisible? LLM visibility is the new competitive advantage, and it is not measured in Google Analytics or traditional SEO tools.
Why AI visibility is decisive in 2026
Buying decisions are increasingly based on recommendations from ChatGPT, Gemini, Copilot, Claude and Perplexity. Research shows that over 60% of Google searches are now zero-click — the user gets the answer directly from AI without clicking through. For B2B businesses, this means the first — and often decisive — contact with your brand happens in an AI conversation you cannot see. GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) are the strategies that ensure you win these moments.
What affects AI visibility?
AI visibility is affected by five key factors: 1) Structured content — FAQPage JSON-LD, Organization JSON-LD and llms.txt that make information machine-readable. 2) Authority — links and mentions from credible external sources. 3) Consistency — the same information across all digital platforms. 4) Relevance — content that explicitly answers the questions your target audience asks AI. 5) Continuous optimisation — AI models are updated and competitors are working. Periscopify measures all five factors and identifies what delivers the greatest effect.
