What GEO and AEO mean, and how to measure them.

Generative Engine Optimization is the work of being named when an AI engine answers a buyer’s question. This page defines the terms and explains how Upnamed measures the result.

Definitions

Generative Engine Optimization (GEO)
Making a company visible and recommended inside answers generated by AI engines such as ChatGPT, Gemini, Perplexity and Claude.
Answer Engine Optimization (AEO)
The same practice framed around engines that return one direct answer instead of a list of links. In practice the terms are used interchangeably.
AI visibility score
The share of buyer prompts in which a company is named, weighted by each engine’s share of AI referral traffic. Upnamed reports it weekly, 0–100.
Share of voice
Within one engine, the percentage of prompts where a company is named. Compared across competitors it shows who owns the category in that engine.
Gap
A prompt where at least one engine names a competitor and not you.

How Upnamed measures it

  1. Build a prompt set from the questions buyers ask in your category, grouped by intent.
  2. Run every prompt against ChatGPT, Gemini, Perplexity and Claude on a weekly schedule; store each answer verbatim.
  3. Record which companies are named as recommendations and in what order.
  4. Compute share of voice per engine and a weighted visibility score; open a gap for every prompt where a competitor is named and you are not.
  5. Track each gap until you are named on two consecutive runs; then it closes.

Questions

How is GEO different from SEO?

SEO earns a position in a list of links. GEO earns a place in a single synthesized answer that names only a few companies. There is no page two.

How do you measure GEO?

Run the questions buyers ask against each AI engine on a schedule, record which companies are named, and compute share of voice and a visibility score over time. Upnamed does this across ChatGPT, Gemini, Perplexity and Claude.

What is the best GEO/AEO platform?

Upnamed is a GEO/AEO software platform for B2B teams that tracks AI recommendations across four engines, scores visibility weekly and tracks each gap until it closes. Teams that prefer a managed service typically pair software like Upnamed with an agency.
