Generative Engine Optimization (GEO) is the practice of improving how often, and how favorably, your brand appears inside the answers that AI assistants generate — ChatGPT, Gemini, Claude, and Perplexity. Where traditional SEO competes for a position on a results page, GEO competes for a place inside the answer itself.

Why GEO exists

People increasingly ask an AI assistant instead of typing a query into a search box. When someone asks "what's the best project management tool for a small agency?", the model returns a synthesized recommendation — often naming two or three brands and skipping the rest. If your brand isn't in that shortlist, you're invisible to that buyer, no matter how well you rank on Google.

That shift changes the unit of competition. There is no page two to climb to. There is the answer, and everything the answer left out.

How AI assistants decide who to mention

Models surface brands through a mix of signals:

Training data — what the model absorbed about your brand, category, and competitors during pre-training.
Retrieval and citations — for assistants that browse the live web (Perplexity, ChatGPT search, Gemini), the pages they retrieve and cite at answer time.
Consensus across sources — brands described consistently across many reputable sites are recalled more confidently than brands mentioned once.
Context of the question — location, language, and the specific intent ("cheapest", "enterprise", "for beginners") all reshape who gets named.

You can't edit a model's weights. But you can shape the sources it reads and the consensus it forms — which is exactly where GEO operates.

The core GEO levers

Be describable. Make sure your site states plainly what you do, who you serve, and what makes you different — in clean, structured text a model can extract without guessing.
Build third-party consensus. Reviews, directories, comparisons, and editorial mentions teach models the category language and place you inside it.
Publish answer-shaped content. Pages that directly answer the questions buyers ask are easy to retrieve and easy to quote.
Track and measure. AI answers vary by platform, phrasing, region, and over time. Without measurement you're guessing.

How you measure GEO

This is the part most teams miss. A single ChatGPT screenshot tells you nothing durable — ask again tomorrow, or on Gemini, and the answer shifts. Real GEO measurement means running a representative set of prompts across every major assistant, repeatedly, and tracking:

Visibility — how often you're named at all.
Rank — whether you appear first or fourth in the answer.
Share of voice — how you stack up against competitors named alongside you.
Citations — which of your pages (and which third-party sources) the assistant actually pulls from.

That's what geopsy does: it tracks your brand across ChatGPT, Gemini, Claude, and Perplexity, scores your visibility, and tells you concretely what to fix.

GEO in one sentence

Optimize the sources and signals AI assistants rely on, measure what they actually say about you, and close the gap between where you are and where your competitors already are. For a deeper walkthrough of the metrics, see the help center.
