GEO and AEO: the new search stack for AI-native brands.
Citation-rate has replaced rank-position. Here's how we instrument content for ChatGPT, Perplexity, and Google AI Overviews — and what we measure.
Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO) are the disciplines of getting cited by AI engines like ChatGPT, Perplexity, and Google AI Overviews. The new metric is citation rate, not search rank. Content earns citations through answer capsules at the top, structured data, fresh first-party data, clear entity definitions, and authoritative authorship — most of which traditional SEO already encourages but hasn't optimized for.
Search isn't dying. It's fragmenting. Google AI Overviews, ChatGPT, Perplexity, and Claude all surface answers in different places and cite different sources. The brands winning the next phase aren't the ones ranking #1 — they're the ones being cited by the engines that mediate research.
What changes.
Click-through is no longer the only metric. AI engines often answer a question without the user clicking anywhere. The win is being the cited source — your name, your data, your framing — appearing in the answer the user reads. This is generative engine optimization (GEO), and answer engine optimization (AEO) is its cousin focused on direct-answer formats and featured snippets.
What gets cited.
Across thousands of citations we've measured, the patterns are consistent: pages with a clear answer capsule at the top get cited 30–40% more often. First-party data and original benchmarks dramatically increase citation likelihood — engines prefer authoritative sources over aggregations. Structured data (Article, FAQPage, HowTo) makes content extraction-ready. Recently published, frequently updated content earns more Perplexity citations specifically.
The instrumentation layer.
Track citation rate per AI engine, not just rank in Google. Measure what queries your brand appears in, what queries it should appear in but doesn't, and which content gets cited most. The tooling is young but real: Otterly, Profound, and Evertune all do versions of this. Measure weekly, not quarterly.
AEO/GEO isn't replacing SEO. It's running on the same foundation — clean structure, schema, semantic HTML — but optimizing for a different success metric: citation, not click.
Where to start.
Pick your three most important queries. Open ChatGPT, Perplexity, and Google AI Overviews. Are you cited? If not, who is? What does their content do that yours doesn't? Most of the time, the answer is: their first 80 words directly answer the question, and yours don't. Fix that on your top 10 pages and you'll see citations within 4–8 weeks.
RAG vs agents vs fine-tuning: when each one wins.
