The short answer
GEO (Generative Engine Optimization) is the practice of making your content visible, quotable and recommended inside AI-generated answers — in ChatGPT, Gemini, Claude, Perplexity and Google's AI Overviews. Where SEO optimizes for a list of blue links, GEO optimizes for being the answer.
One sentence: SEO gets you ranked; GEO gets you cited.
Why it matters now
A growing share of product research, comparisons and how-to questions never reach a classic results page. The AI engine answers directly and cites a handful of sources. If your client isn't in that handful, they're invisible to that customer — regardless of their Google ranking.
GEO vs. SEO — what actually changes
- Unit of competition: SEO competes for positions; GEO competes for share of answer and citations.
- Content shape: engines quote well-structured, answer-shaped, entity-clear passages — not walls of text.
- Technical layer: classic crawlability still matters, plus new signals: llms.txt, schema depth, chunkability, and whether LLM crawlers can render your pages at all.
- Measurement: rank trackers can't see AI answers. You need prompt-based monitoring across platforms — measured with prompts that reflect real buying intent.
What doesn't change
The foundation. Sites that are fast, crawlable, well-structured and genuinely authoritative win in both worlds. That's why every GEO project should start with a technical SEO/GEO audit — most "AI visibility problems" turn out to be fixable technical and content-structure problems.
How teams do GEO in practice
- 1. Audit the foundation — 100+ technical aspects, from crawlability to llms.txt and schema coverage.
- 2. Define the prompts that matter — real customer questions across buying stages, per platform (this is PromptDNA™).
- 3. Measure share of answer — daily, across ChatGPT, Gemini, Claude and Perplexity.
- 4. Close the gaps — answer-shaped content, entity clarity, citable structure; briefs generated from findings.
- 5. Prove it — before/after citation and share-of-answer deltas in client reports.
Rule of thumb: if a page can't be quoted in two sentences, an LLM won't quote it at all.
