Generative Engine Optimization (GEO)

Definition

Generative engine optimization (GEO) is the practice of making content and product data likely to be retrieved, cited and recommended by AI answer engines — ChatGPT, Google AI Mode and AI Overviews, Gemini, Perplexity — rather than ranked in a list of links a person then clicks.

The shift it responds to: when a model answers the question directly, the click that used to be the objective may never happen. Being the source the model used replaces being the result the user clicked.

How it differs from SEO

Most classic SEO fundamentals still apply — crawlability, structure, authority, freshness. Three things differ materially:

• Extraction beats persuasion. A model lifts a claim, a number, a specification. Copy engineered to build desire across three scrolls extracts poorly. A clear declarative sentence with the number in it extracts well.
• Structure carries more weight. Structured data, clean headings, and typed attributes are how a model reliably locates the fact it needs. Prose that buries the specification is invisible to it.
• The unit is the passage, not the page. Optimising a page as a whole matters less than whether individual passages stand alone as citable, self-contained answers.

In commerce specifically

For merchants, GEO collapses substantially into the product feed problem: agents compare on attributes, not adjectives. A product missing the dimension a comparison turns on is excluded before quality is assessed.

Beyond the feed, the levers that matter are consistent product naming across the web, specification data that agrees between your site and your marketplace listings, and answering the comparison questions buyers actually ask in a form a model can lift.

What is genuinely uncertain

Anyone presenting GEO as a solved discipline with reliable tactics is ahead of the evidence. Measurement is immature, the engines change behaviour without notice, and there is no equivalent of rank tracking with a decade of methodology behind it.

Our position: treat GEO as structured-data hygiene plus citable writing, both of which have independent value, and be sceptical of tactics that only pay off if a specific engine keeps behaving a specific way.

What it does not mean

It does not mean generating more content. Volume was a weak strategy in SEO and is a worse one here, where a model is selecting a source rather than filling a page of results. One accurate, well-structured specification table outperforms ten articles about the category.
