Definition
What this term means
The percentage of relevant AI-generated responses that include a reference, link, or attribution to your brand or content. Citation rate is measured by testing a set of category-relevant queries across AI platforms and tracking how often your brand appears as a cited source. It is one of the most direct indicators of AI visibility performance.
Why it matters
The business impact
Citation rate is the closest metric to a conversion rate for AI visibility. A higher citation rate means more users see your brand as a trusted source at the moment they are making decisions. Tracking citation rate over time, across platforms, and against competitors provides actionable insight into which optimisation strategies are working and where gaps remain.

Model Citation
An instance where an AI model references, quotes, or links to a specific source when generating its response. Model citations can appear as inline references, linked source lists, or attributed quotes, and they represent the AI equivalent of earning a backlink in traditional SEO. Platforms like Perplexity and Google's AI Overviews prominently display citations.
AI Visibility Score
A composite metric that quantifies how visible, accurate, and favourably positioned a brand is across AI-generated responses. The AI visibility score typically combines multiple factors, including citation frequency, recommendation position, accuracy of brand description, sentiment, and share of model, into a single trackable number that can be monitored over time and benchmarked against competitors.
Authority Signals
The collective evidence that demonstrates a brand's credibility, expertise, and trustworthiness to AI systems and search engines. Authority signals include expert authorship with verifiable credentials, citations from reputable sources, industry awards, professional certifications, longevity of domain, quality of backlink profile, and consistent representation across authoritative platforms such as Wikipedia, industry publications, and government databases.
