GEO & AI Search Glossary
Essential vocabulary for marketers navigating the AI-first search landscape — from LLMs to AI visibility scores.
A
AI Answer
The natural-language response generated by an AI engine (ChatGPT, Claude) in response to a user query. Unlike a list of blue links, an AI answer synthesizes information and presents a direct recommendation or explanation. AI answers are increasingly the first — and sometimes only — content a buyer sees.
What is GEO? →AI Citation
A reference to a source within an AI-generated answer. AI engines cite web pages, articles, or brand websites when they include claims drawn from those sources. Earning AI citations is a core GEO objective because they drive direct brand awareness and referral traffic.
OUTRANKgeo Features →AI Overview (Google)
Google's AI-generated summaries that appear at the top of search results pages, synthesizing answers from multiple web sources. Formerly known as Search Generative Experience (SGE). Brands featured in AI Overviews gain high-visibility placement without requiring users to click through.
GEO vs SEO →AI Recommendation
An explicit or implicit endorsement of a product, tool, or brand within an AI-generated answer. When a buyer asks an AI engine which software to use for a given problem, the AI recommendation is the most valuable placement a B2B brand can earn — equivalent to a high-intent sales conversation.
Track AI Recommendations →AI Search
A category of search technology that uses large language models to generate direct answers to queries, replacing or augmenting traditional ranked link lists. Platforms like ChatGPT and Claude are examples of AI search engines. AI search is reshaping how B2B buyers research and evaluate software.
Intro to GEO →AI Visibility Score
A 0–100 metric that quantifies how often and how prominently a brand appears in AI-generated answers for a defined set of target queries. OUTRANKgeo calculates this score by aggregating mention frequency, position in responses, and query coverage across monitored AI platforms.
How Scoring Works →AI-First Marketing
A marketing strategy that prioritizes visibility in AI-generated content over traditional search rankings. AI-first marketers optimize for brand mentions in LLM responses, structure content to be citation-friendly, and measure success through metrics like AI visibility score rather than keyword positions.

Brand Mention
Any reference to a brand name within an AI-generated answer. Brand mentions are the primary unit of measurement in GEO. OUTRANKgeo tracks not just whether a brand is mentioned, but also the sentiment, context, and accuracy of each mention — including whether the AI is saying something factually incorrect.
Monitor Brand Mentions →Brand Positioning (AI)
How a brand is described, categorized, and compared in AI-generated responses. AI models form implicit brand positions based on training data and retrieval sources. GEO strategy aims to shape brand positioning in AI answers by ensuring authoritative, accurate, and consistent information exists in the sources AI models trust.
GEO Strategy →C
ChatGPT SEO
The practice of optimizing for brand visibility specifically within ChatGPT responses. Because ChatGPT uses Bing search and its own training data to answer queries, ChatGPT SEO involves being cited in Bing-indexed content, industry review sites, and authoritative publications that ChatGPT tends to reference.
Track ChatGPT Visibility →Claude SEO
Optimization strategies targeted at improving brand visibility in Claude (Anthropic) responses. Claude's answers are grounded in its training data and, increasingly, real-time retrieval. Brands improve Claude visibility by earning coverage in sources Anthropic's training pipeline favors — quality publications, structured documentation, and expert commentary.
Monitor Claude Visibility →Competitor Analysis (AI)
The process of tracking which competitor brands appear in AI-generated answers alongside or instead of your own brand. OUTRANKgeo's competitive benchmarking shows how often each competitor is mentioned in the same queries as your brand, giving a side-by-side share-of-voice view across AI platforms.
AI Competitor Tracking →G
Generative Engine Optimization (GEO)
The discipline of improving a brand's visibility and favorability in AI-generated answers from large language models and AI search engines. GEO is the counterpart to SEO for the AI-first search era, focusing on brand mentions in ChatGPT and Claude rather than traditional search engine rankings.

Large Language Model (LLM)
A neural network trained on massive text corpora that can generate human-like text, answer questions, and synthesize information. GPT-4 (OpenAI) and Claude (Anthropic) are examples. LLMs power AI search engines, and understanding how they select and cite information is foundational to GEO strategy.
GEO & LLMs Explained →M
Multi-Engine Scan
A single scan run by OUTRANKgeo that fires your query set at multiple AI platforms simultaneously — ChatGPT and Claude — and aggregates the results. Multi-engine scanning gives a comprehensive view of your brand's AI visibility across the platforms your buyers actually use.

Query Template
A reusable prompt pattern representing the types of questions a potential buyer might ask an AI engine when researching your product category. OUTRANKgeo provides a query library of battle-tested templates. Selecting the right query templates is the foundation of an accurate GEO measurement program.

Retrieval-Augmented Generation (RAG)
A technique where an AI model retrieves relevant documents from a live knowledge base before generating a response, grounding its output in up-to-date information. Many AI search engines use RAG to ensure their answers are factually current. Understanding RAG helps GEO practitioners optimize the content assets AI models retrieve.
GEO Technical Deep-Dives →V
Visibility Trend
The change in a brand's AI visibility score over time, measured week-over-week or month-over-month. OUTRANKgeo visualizes visibility trends to show whether GEO initiatives are moving the needle and to surface correlations between content changes and shifts in AI mention frequency.
Track Visibility Trends →Z
Zero-Click Search
A search interaction where the user receives a complete answer without clicking any result link. AI search dramatically increases zero-click rates because the AI answer itself resolves the query. For brands, this means the AI mention — not the click-through — is the primary value unit, making GEO measurement essential.
