Two things now decide whether a buyer finds you. They are related, they are not the same, and most companies are only working on one.
SEO, search engine optimization. Optimizes to appear in a ranked list of links. The buyer types keywords, gets a page of results, and chooses one. You compete for position. Success is a click.
GEO, generative engine optimization. Optimizes to be named inside an AI-generated answer. The buyer asks a full question in ChatGPT, Perplexity, Gemini, or Google's AI Overview and gets one synthesized paragraph that names a few companies. You compete for inclusion. Success is a mention.
The practical difference is the failure mode. In search, ranking eleventh means fewer clicks. In an AI answer, not being named means you are absent entirely, and unlike a low ranking, you never see it happen.
| SEO | GEO | |
|---|---|---|
| What the buyer gets | A ranked list of links | One synthesized answer |
| What the buyer types | Keywords | A full question |
| You compete for | Position | Inclusion |
| Driven by | Keywords, backlinks, on-page relevance | Entity clarity, corroboration, quotable content |
| Measured by | Rank, clicks, traffic | Mentions, citations, share of answer |
| Failure looks like | Lower on the page | Absent, invisibly |
What generative engines weigh. Clear identity, stated plainly enough that a machine cannot misread who you are and what you do. Structured data, the markup that states it in a form engines read directly. Corroboration, meaning third parties across the web describe you the same way you describe yourself. Reviews and local authority, which lift classic ranking and AI citation at the same time. And content written to answer the exact questions buyers ask, in a format an engine can quote.
Where they overlap. Most of it. Clean site structure, credible content, and third-party trust serve both. GEO does not replace SEO. Blue-link search still drives the most qualified traffic today; GEO is the faster-growing share and the one where real-world credibility compounds. You need both.
How to check where you stand. Ask an AI engine three questions, in order. First, about your company by name. Most companies pass this one, and it only reaches buyers who already know you. Second, for the best provider in your category and market. This is where you find out whether it names a competitor instead. Third, the problem your buyers have, without naming a category at all. In most industries almost nobody has written for that question, which makes it the open lane.
