AI Search Strategy. GEO + AEO, explained.
Search is splitting in two. Traditional rankings still matter — but AI engines now answer questions directly, and they choose which brands to cite. If your business is not structured for AI retrieval, you are losing visibility to competitors who are.
This page is a strategy hub, not a service page. It explains how the two AI-search disciplines we offer fit together — and routes you to the dedicated service page for the one your business needs first. The two services are Generative Engine Optimization (GEO) for being cited by ChatGPT, Perplexity, Gemini, and Claude, and Answer Engine Optimization (AEO) for capturing featured snippets, voice search, and zero-click answer boxes. Most engagements need both, but each starts with a single primary discipline based on where your business is today.
Measurement is productized as Reef Citation Index™ — Nekko’s proprietary AI-citation visibility tracker. Every GEO and AEO engagement reports against the Index methodology, and the published benchmark establishes the public baseline for Hawaii businesses. No one can guarantee placement in AI answers or search results, and we don’t. We do the work that makes it more likely, and we report what changed.

How AI Engines Decide Who to Cite.
AI search engines do not rank pages. They retrieve passages, evaluate credibility, and synthesize answers — citing only the sources they trust most.
1
Query Fan-Out
The AI expands a single user query into 10–20 sub-queries covering adjacent intents, definitions, and comparisons.
2
Passage Retrieval
Specific passages — not full pages — are retrieved based on semantic similarity. Self-contained sections with clear headings win.
3
Authority Scoring
Retrieved passages are scored for E-E-A-T signals: author credentials, structured data, corroborating sources, and freshness.
4
Synthesis & Citation
The AI writes a response from the highest-scoring passages and cites its sources. Being cited requires being the most authoritative answer.
For the full technical deep-dive, read the AI Search Manual or use the AI Search Playbook as a quick reference.
What’s the Difference Between GEO and AEO?
GEO and AEO are not competing strategies — they are complementary layers built on the same foundation of traditional SEO. Each has its own dedicated service page below — pick the one that matches where your business needs visibility first, or contact us to map both into a single engagement.
