Definition
Answer engine citation share is the percentage of responses to a defined prompt set, run against answer engines like ChatGPT, Perplexity, and Google AI Overviews, that cite URLs from a given brand, used as the primary AEO north-star metric in 2026.
In Depth
Citation share is computed as cited-responses divided by total-responses, per brand, per engine, per prompt set. It handles the reality that different engines retrieve differently, so breakouts per engine matter. A healthy program tracks share across at least three engines and at least 50 prompts per category. Scavio's ask endpoint provides the raw data per engine; the aggregation happens in a downstream analytics pipeline.
Example Usage
The marketing lead reviewed answer engine citation share every Monday and watched the brand's share climb from 8% to 34% inside Perplexity.
