When your customers have a question today, a growing share of them don't type it into Google — they ask ChatGPT, Gemini or Perplexity, and read the one answer that comes back. If your brand isn't in that answer, you were never considered.
GEO — Generative Engine Optimization — is the practice of earning a place in those answers.
GEO vs SEO: same family, different target
SEO optimizes for a ranked list of links. Success means appearing on page one of Google, and the user still chooses which link to click.
GEO optimizes for a composed answer. The AI engine reads a handful of sources, writes one response, and may mention or cite a few brands by name. There is no page two. Either the answer includes you, or it doesn't.
The two are complementary rather than competing. Much of what makes a site good for SEO — crawlable pages, clear structure, real content — also helps GEO. But GEO adds requirements SEO never had:
- AI crawler access. ChatGPT, Claude, Perplexity and others use their own crawlers (GPTBot, ClaudeBot, PerplexityBot and more). A robots.txt written years ago may block them without anyone noticing.
- Extractable answers. AI engines lift sentences, not pages. A page whose key facts are buried in marketing prose gives the engine nothing to quote.
- Verifiable substance. Engines favor statements with concrete, checkable details — what you do, where you operate, what it costs — over slogans.
What GEO work actually looks like
In our delivery practice, GEO breaks down into four layers:
- Access — making sure AI crawlers are allowed in and can find your pages (robots.txt, sitemap, server behavior).
- Readability — server-rendered HTML with clean titles, descriptions, headings and structured data, so a machine reading your page without JavaScript still gets the full story.
- Citability — content written so a sentence can be lifted whole: category + location + hard numbers, FAQ answers that stand alone, facts stated plainly.
- Corpus — enough real pages (guides, service pages, articles) that an engine judging "is there evidence behind this site?" finds more than a homepage.
What GEO cannot do
Honesty matters here. GEO does not manufacture demand — it connects you to questions people are already asking. It cannot guarantee that any specific engine will cite you, and anyone promising a guaranteed citation rate is selling something else. What you can verify is the groundwork: whether AI crawlers can reach you, whether your pages read cleanly, and — over weeks, not days — whether mentions start appearing when you test the questions your customers actually ask.
That last part is measurable. We track it monthly, and we recommend anyone doing GEO work do the same: pick the real questions, ask the engines, record the answers, repeat.
