What is GEO for pharma?

Generative Engine Optimization (GEO) for pharma is the practice of measuring and improving how generative AI engines — ChatGPT, Claude, Gemini, Perplexity and others — cite, rank and describe pharmaceutical brands. It is distinct from classical SEO because LLMs answer rather than rank, and the visibility unit is the citation, not the click.

How is AEO different from SEO?

Answer Engine Optimization (AEO) is the discipline of structuring content so it is selected as the authoritative answer by AI engines and AI Overviews. SEO targets ranked search results pages. AEO targets the synthesised AI answer itself. Both matter for pharma, but AEO requires explicit claim sentences, structured data, and authoritative source citations.

Which LLMs does PharmaGEO track?

PharmaGEO tracks pharma brand visibility across eight LLMs: ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), Perplexity, Mistral, Grok (xAI), Copilot (Microsoft) and DeepSeek.

Is PharmaGEO MLR-compliant?

Yes. PharmaGEO output is structured for Medical, Legal and Regulatory (MLR) review. Findings are evidence-traceable to source URLs, prompts are auditable, and the platform does not generate promotional content — it measures and audits external AI behavior about a brand.

Who is PharmaGEO for?

PharmaGEO is built for pharma brand teams, medical affairs, digital and omnichannel, regulatory affairs, and pharmacovigilance teams who need to understand how AI search engines treat their brand, indication or therapeutic area.

What is the PharmaGEO Index?

The PharmaGEO Index is the first public ranking of pharma brand visibility in AI answers. It benchmarks 23 brands across four therapeutic areas and three AI engines (ChatGPT, Gemini, Perplexity) using 80 standardised prompts per brand and a six-axis scoring methodology.

See how AI actually talks about your pharma brand.

PharmaGEO is the specialised AI visibility, Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO) tracker dedicated to the life-science industry.

Why GEO matters

HCPs and patients are asking AI first.

SEO ranks pages. LLMs rank answers. They remix and re-rank sources differently, so being on Google page 1 no longer guarantees you are in the answer at all.

Why PharmaGEO

Built for pharma. Not retrofitted for it.

Generic GEO tools track consumer brands across ChatGPT and Perplexity. Pharma needs more: indication-level analysis, clinical LLM coverage, pharmacovigilance, and MLR-ready output.
