The AI search glossary.

Plain-language definitions for GEO, AEO, AI SEO, LLMO, and the rest of the vocabulary that has shown up in B2B marketing in the last 18 months.

GEO (Generative Engine Optimization)

The practice of getting cited by name in answers from generative AI engines like ChatGPT, Perplexity, Gemini, and Claude. The companion practice to SEO.

AEO (Answer Engine Optimization)

A near-synonym for GEO. AEO emphasizes optimization for answer-style results (Google AI Overviews, featured snippets, AI assistant answers). In practice the work overlaps almost entirely with GEO.

AI SEO

The umbrella term covering traditional SEO plus GEO and AEO as a single integrated practice. An "AI SEO agency" runs all three together against the same scorecard.

LLMO (Large Language Model Optimization)

Another near-synonym for GEO, focused specifically on optimizing for the large language models that power AI search.

AI Visibility

A measurement category. The percentage of category-relevant AI prompts that surface your brand by name. The Reneka audit benchmarks AI visibility across ChatGPT, Perplexity, Gemini, and Claude.

Citation Share of Voice

The percentage of AI answers in your category that cite your brand by name, benchmarked against named competitors. Reneka's headline metric for AI search performance.

Citation Surface

The set of third-party domains that show up in AI answers in your category. Different from your backlink profile because AI assistants cite from different sources than Google ranks.

Entity Statement

A Wikipedia-style opening sentence that names the brand, says what it does, and where it is based. Retrieval models lift these verbatim. Every Reneka site has one.

AAIA Framework

Reneka's four-stage GEO methodology: Audit, Architect, Implement, Amplify. See the methodology page.

AI Overviews

Google's AI-generated answer summary at the top of search results. Optimizing for AI Overviews is part of the AEO practice.
