AI & AEO

AI Citation Share

Quick Definition

AI citation share is the percentage of AI-generated answers (across ChatGPT, Perplexity, Gemini, Copilot, AI Overviews) for a defined query set that cite your domain among the listed sources.

In context

AI citation share is the AEO equivalent of share of voice in classical SEO. Measurement: define a representative query set in your category, probe each across multiple AI engines monthly, and count the share of probes where your domain appears in the cited sources. Industry benchmarks vary widely — for a category-defining brand, healthy AI citation share is 20%+ on top-of-funnel queries. Tracking it monthly over time is the only way to know whether your AEO investments are working.

Example

A Canadian B2B SaaS tracks AI citation share monthly across 50 category-defining queries on 5 AI engines — climbing from 4% to 28% over 9 months of comparison-content investment.

Retrieval-Augmented Search

Retrieval-augmented search uses a search component to retrieve current relevant documents, which an LLM then uses to compose an answer with citations.

Citation Staleness

Citation staleness is the gap between when AI engines were last updated to reflect your latest content and when those citations actually reflect current information — typically days to weeks for dominant AI search surfaces.

Multi-Step Reasoning

Multi-step reasoning is when an LLM works through a problem across several intermediate steps rather than producing a single shot answer, increasing accuracy on complex queries.
