What is GEO (Generative Engine Optimization)?

GEO is the set of practices that make a brand, product or site more likely to be cited by language models (LLMs) such as ChatGPT, Gemini and Perplexity when they answer user questions.

What is the difference between SEO and GEO?

SEO optimizes for appearing on search engine results pages (SERPs). GEO optimizes for being cited in AI-generated answers. A site can rank well on Google and be invisible to ChatGPT — and vice versa.

How do I know if my brand appears in ChatGPT or Gemini?

The rigorous way is to run sector-relevant prompts systematically and analyse the responses. LLMscope automates this process, testing your brand across multiple LLMs and returning a GEO Score with frequency, tone and relative position data.

What is the GEO Score?

The GEO Score is a 0–100 metric measuring a brand's organic visibility in LLM responses. It combines mention frequency, relative position in the answer, and citation quality/tone.

What is RAG-Readiness?

RAG-Readiness measures whether site content is structured to be effectively retrieved by RAG (Retrieval-Augmented Generation) systems — the technology LLMs use to access up-to-date information. A site can have high RAG-Readiness but a low GEO Score, meaning the content exists but has not yet been incorporated into the models.

Is GEO the same as AEO?

Not exactly. AEO (Answer Engine Optimization) focuses on appearing in featured snippets and direct answers from traditional search engines. GEO focuses specifically on generative LLMs. There is overlap in techniques, but the evaluation mechanisms differ.

How long does it take to see results in GEO?

The web search layer (Perplexity, ChatGPT with search) can change in days or weeks because it depends on traditional SEO. The organic layer — what the model learned during training — changes on model retraining cycles, which can take months. There is no shortcut to organic visibility in LLMs.

Do I need GEO if I already have good SEO?

Strong SEO helps the web search layer but does not guarantee organic visibility in LLMs. Models learned from a specific slice of the internet and have their own criteria for authority. There are companies ranked #1 on Google that are invisible in ChatGPT. They are complementary disciplines, not substitutes.
