The short answer
Key takeaways
- Track three things: citation share of voice, source-URL inclusion, and sentiment.
- Distinguish mentions (no link) from citations (linked) — only citations send clicks.
- Position matters: the first entity named is often treated as the default recommendation.
- A manual prompt test (3–5 runs each) gives a real directional baseline in an afternoon.
You can’t optimize what you can’t see. As discovery shifts into AI answers, “where do I rank?” becomes “how often am I cited, and how am I described?” This guide gives you a measurement framework you can start today — part of our complete GEO guide.
What to measure: the three metrics that matter
- Citation share of voice. For a fixed set of prompts, how often is your brand cited versus each competitor? This is the closest equivalent to “rank” in AI search.
- Source-URL inclusion. Which specific pages of yours get pulled into answers? This tells you what content the engines trust — and what to make more of.
- Sentiment & position. How are you described, and are you named first? Models tend to treat the first entity mentioned as the default recommendation.
Mentions vs citations — don’t conflate them
A citation links to your page and can drive measurable referral traffic. A mention names you without a link. The ratio differs by engine: ChatGPT frequently mentions brands without linking, while Perplexity cites sources more consistently. Track both, because they do different jobs — citations win clicks, mentions build the brand association that makes you the default answer over time.
A free baseline you can run today
| Step | What to do | What you learn |
|---|---|---|
| 1. Pick prompts | List 15–30 questions a buyer would ask that you should win | Your real AI “keyword” set |
| 2. Run them 3–5× each | Ask in ChatGPT and Perplexity; answers vary, so repeat | A stable appearance rate, not a one-off |
| 3. Record results | Appear? Position? Competitors named? Sources cited? | Citation share of voice + gaps |
| 4. Add Search Console | Watch impressions/clicks on Overview-triggering queries | Google AI surface trend over time |
When to move from manual to tooling
Manual testing gives you direction; tools give you reliability, history, and competitor benchmarking. When you need statistically meaningful rates across many prompts and engines, move to a tracker — see our neutral rundown of the best GEO tools for the options at each budget. The engine that matters most after Google is usually Perplexity, because it cites and clicks — here’s how to appear in Perplexity.
