GEO Glossary

Plain-English definitions for Generative Engine Optimization, AI search, and citation ranking — everything you need to talk GEO with confidence.

A

AI Citation: An instance where an AI answer engine references, quotes, or links to your content when responding to a user query. The primary success metric for GEO campaigns.
AI Overview: Google's AI-generated summary that appears at the top of search results for many queries. Powered by Gemini, AI Overviews synthesize multiple sources into a single answer, citing the sources it draws from. Appearing in AI Overviews is a key GEO goal for SEO practitioners.
Answer Engine: A search or discovery product that returns direct answers instead of a ranked list of links. Examples include Perplexity, ChatGPT Search, and Google AI Overviews. Sometimes called a "generative search engine."

Brand Mention: An instance where an AI response names your brand — even without a clickable citation link. Brand mentions influence user perception and are tracked separately from formal citations in GEO programs.

Citation Frequency: How often your brand, product, or content is cited by an AI answer engine across a set of tracked queries over a given time period. The primary KPI in a GEO program.
Citation Rate: The percentage of tracked queries that return a citation for your brand or content. Calculated as (queries with at least one citation) ÷ (total tracked queries).
Competitive Benchmarking (GEO): Tracking how often competitors are cited by AI engines for the same queries you are targeting, used to identify gaps and prioritize content efforts.
Content Freshness: How recently a piece of content was published or updated. AI engines weight freshness when selecting sources for time-sensitive queries. Maintaining up-to-date content is critical for sustained citation rates.

Generative Engine Optimization (GEO): The practice of structuring and optimizing content so AI-powered answer engines — such as ChatGPT, Perplexity, and Google AI Overviews — cite your brand or content in their responses. Analogous to SEO for traditional search, but optimized for citation probability rather than ranking position.
GEO Score: A composite metric (used by GEOCraft) that measures how well a brand or domain is positioned to be cited in AI answers. Combines citation frequency, topic coverage, source authority, and content freshness into a single 0–100 score.
GEO Refresh: A re-optimization cycle triggered when a piece of content's citation rate drops below a threshold. The content is updated, expanded, or restructured to regain citation probability without changing its URL.

Ideal Customer Profile (ICP): A detailed description of the company or persona most likely to become a high-value customer. In GEO, the ICP informs which queries and topics to prioritize so AI citations reach the right audience.

Large Language Model (LLM): A neural network trained on large text corpora capable of generating fluent natural-language responses. Powers products like ChatGPT (GPT-4o), Claude, and Gemini. GEO targets the retrieval and citation behavior of LLM-based products, not the model weights directly.

Perplexity: An AI answer engine that responds to queries by synthesizing real-time web results. Perplexity cites its sources inline, making it a key channel to track in a GEO program.

Query Set: A curated list of prompts or questions used to regularly probe AI engines for citations. A well-designed query set covers your core topics, buying-stage queries, and competitor comparison queries.

Retrieval-Augmented Generation (RAG): An AI architecture in which a language model fetches relevant documents at inference time and incorporates them into its response. Most modern answer engines (Perplexity, ChatGPT with browsing) use RAG. Content that is well-indexed, authoritative, and clearly structured is more likely to be retrieved and cited.

Share of Voice (AI): The proportion of AI citations within a topic or keyword set that mention your brand versus competitors. An adaptation of the traditional marketing metric for the AI answer era.
Source Authority: The perceived credibility and expertise of a content source, inferred by AI engines from signals like domain authority, citation history, author credentials, and content depth. High source authority increases citation probability.
Structured Content: Content organized with clear headings, definitions, bullet points, and explicit claims. Structured content is easier for RAG systems to parse and excerpt, improving citation probability compared to dense prose.

Topic Coverage: The breadth of queries and subtopics for which your content can plausibly be cited. Expanding topic coverage — by publishing content across related terms — is a core GEO growth lever.
