What is AI Visibility?
AI Visibility is the umbrella concept that encompasses all aspects of a brand's presence in AI-generated responses. While individual metrics like Share of Model and Citation Rate measure specific dimensions, AI Visibility captures the holistic picture: how often your brand appears, how accurately it is described, how favourably it is positioned, and how consistently it is represented across all major AI engines.
AI Visibility has multiple dimensions. Quantitative visibility measures how frequently your brand is mentioned (Share of Model) and cited (Citation Rate). Qualitative visibility assesses the accuracy and sentiment of brand descriptions. Competitive visibility compares your presence against competitors across the same query set. And temporal visibility tracks how your AI presence evolves over time, particularly around model updates and content changes.
Monitoring AI Visibility requires systematic measurement across all major answer engines. A brand might be highly visible on ChatGPT (due to training data associations) but poorly visible on Perplexity (due to weak citation signals). Understanding these variations allows brands to target their AEO efforts where they will have the most impact.
The concept of AI Visibility also extends beyond traditional brand queries. Brands need visibility in category queries ("best tools for X"), comparative queries ("A vs B"), and informational queries ("how to solve Y") that may lead to brand discovery. A comprehensive AI Visibility strategy addresses all these query types.
Why it matters
AI Visibility is becoming as critical as search visibility for brand discovery. Consumers increasingly start their product research with AI engines, and brands that are invisible in these responses lose access to a growing share of potential customers. Monitoring and improving AI Visibility ensures your brand remains discoverable as consumer behaviour shifts toward AI-first research.

Share of Model
metricShare of Model (SoM) measures how frequently a brand is mentioned or recommended by AI engines in response to relevant queries. It is the AI-era equivalent of Share of Voice, quantifying your brand's presence across ChatGPT, Perplexity, Gemini, Claude, and other answer engines.
Citation Rate
metricCitation Rate measures the frequency at which an AI engine references a specific source domain when generating responses. Unlike Share of Model, which tracks brand mentions, Citation Rate specifically tracks when your website URL or domain is cited as a source.
Competitor Visibility
metricCompetitor Visibility in AEO measures how often and how favourably your competitors appear in AI engine responses compared to your brand. It provides the competitive context necessary to understand whether your AI visibility position is strong, weak, or at risk.
AEO (AI Engine Optimisation)
strategyIn marketing, AEO means AI Engine Optimisation: the practice of improving how a brand appears in AI-generated responses. It is not the customs and trade meaning of AEO. Instead, it focuses on visibility across ChatGPT, Perplexity, Gemini, Claude, and other answer engines.
