# PharmaGEO

> PharmaGEO is the AI visibility, Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO) tracker built specifically for the life-science industry. It measures how ChatGPT, Claude, Gemini, Perplexity, Mistral and four other LLMs cite, rank and describe pharma brands across therapeutic areas, languages and geographies — with MLR-ready output.

PharmaGEO is operated by aikka SAS (Paris, France). The platform combines public pharma signals (FDA labels, EMA, NCCN, ESMO, PMC literature, EFPIA guidance, patient organisations) with original cross-engine benchmarking to produce the first public ranking of pharma brand visibility in AI answers — the PharmaGEO Index.
