Book Your Strategy CallYou measure generative engine optimisation with citation share: the percentage of relevant AI answers in which your brand is named. Where classic SEO is measured in rankings and traffic, GEO is measured by how often you appear inside the answers AI engines give to the questions your buyers ask. It is the metric that tells you whether your brand is winning the AI conversation.
What citation share is
Citation share is simple in principle. Take the set of questions that matter in your market. Ask them across the major AI engines. Record how often your brand is named, and how often each competitor is. The proportion of answers that cite you is your citation share. Tracked over time, it shows whether your visibility in AI is rising or falling, in a way rankings alone cannot.
How to measure it
Build a fixed list of buyer questions, from broad category queries to specific comparisons. Run them regularly across ChatGPT, Perplexity and Google AI Overviews. Log who is cited each time, including competitors, so you have a benchmark. Consistency matters more than volume: the same questions, asked on a regular cadence, reveal the trend. Perplexity is especially useful here because it shows its citations openly.
Why it belongs next to rankings
Rankings and citation share answer different questions. Rankings tell you where you sit in the classic results. Citation share tells you whether you exist in the AI answer that increasingly sits above them. Tracking both gives the full picture of visibility across search and AI. For the wider context, read our GEO guide and our breakdown of GEO versus SEO.
How SugarNova approaches it
We track citation share alongside rankings as a standard part of GEO reporting, so progress is measured by appearances in AI answers, not vanity metrics. See our GEO agency and AI SEO services.

Frequently asked questions
How do you measure GEO?
You measure GEO with citation share: the percentage of relevant AI answers in which your brand is named. You build a fixed list of buyer questions, ask them across the major AI engines on a regular cadence, and record how often you and your competitors are cited.
What is citation share?
Citation share is the proportion of relevant AI answers that name your brand. Tracked over time, it shows whether your visibility inside AI answers is rising or falling.
Which engines should you track?
Track the engines your buyers use, typically ChatGPT, Perplexity and Google AI Overviews. Perplexity is particularly useful because it displays its citations openly.
Should citation share replace rankings?
No, it complements them. Rankings show your position in classic results; citation share shows whether you appear in the AI answer above them. Tracking both gives the full visibility picture.
