Cited-by-AI
Cited-by-AI is the metric that tracks how often an AI engine (ChatGPT, Perplexity, Gemini, Copilot, Claude) names a brand or links to its content as a source inside a generated answer. Unlike traditional rankings, cited-by-AI is measured per prompt and per engine: a brand can be cited first in Perplexity for one query and absent from Gemini for the same query. Why it matters: As zero-click answers consume more of the buyer journey, cited-by-AI share replaces blue-link ranking as the truest measure of search visibility. Tracking it across a defined set of buyer prompts is the foundation of any serious GEO program and the headline metric of an AI visibility audit.
Why Cited-by-AI matters
Earning a citation transforms a brand from a passive search result into an active recommendation endorsed by the AI. This shift is vital because users increasingly treat LLM responses as definitive answers rather than a list of options to explore manually.
In practice
An enterprise SaaS provider uses the Perplexity API to monitor how often their platform appears as a recommended solution in competitive comparison prompts.
Common mistake
Expecting citations to mirror traditional Google Search rankings instead of accounting for the unique training data and real-time retrieval logic of specific LLMs.
How it connects
This metric serves as the performance baseline for Generative Engine Optimization and directly influences the Share of Model voice across various LLMs.
