Quick answer: The core AEO KPIs are mention rate (share of tracked prompts where AI names you), citation share (share of answers that link to your site), share of voice against competitors, average position when named, sentiment, description accuracy, AI referral sessions, conversions from AI referrals, and prompts won or lost month on month. Measure them on a fixed prompt set across the same engines every month.
Rankings and organic clicks still matter, but they no longer tell the whole story. A brand can rank first and be absent from the AI answer above it, or be recommended by ChatGPT without ranking anywhere. AEO needs its own scorecard.
Key takeaways
- Track a fixed set of 20 to 100 prompts across the same engines every month.
- Mention rate and citation share are the two headline metrics.
- Share of voice shows progress against named competitors.
- Accuracy matters: being named with wrong facts can cost sales.
- Tie visibility to business results with AI referral traffic and conversions.
The 9 AEO KPIs
| KPI | How to calculate | What it tells you |
|---|---|---|
| 1. Mention rate | Answers naming you / total answers checked | How often you are in the answer |
| 2. Citation share | Answers linking to your site / total answers | How often your pages are the source |
| 3. Share of voice | Your mentions / all brand mentions in the set | Your visibility against competitors |
| 4. Average position | Mean order in which you appear when named | Whether you are the first or last option |
| 5. Sentiment | Positive, neutral or negative framing, scored | How answers describe you |
| 6. Accuracy | Answers with correct facts / answers naming you | Whether prices, services and locations are right |
| 7. AI referral sessions | Visits from chatgpt.com, perplexity.ai, gemini.google.com, copilot.microsoft.com and similar | Traffic AI sends you |
| 8. AI-assisted conversions | Leads, sign-ups or sales from those sessions | Business value |
| 9. Prompts won and lost | Prompts where you gained or lost a mention since last month | Momentum and what changed |
How do you set up AEO measurement?
- Fix your prompt set. 20 to 100 real buyer questions, grouped by topic and buying stage. See AEO prompt research.
- Fix your engines and markets. For example ChatGPT, AI Overviews, AI Mode, Perplexity and Gemini, in India and the USA.
- Choose competitors. Three to ten brands buyers compare you with.
- Run prompts consistently. Same wording, same engines, similar timing, ideally with a tool.
- Set up analytics. Create an AI referral channel in GA4. See how to track AI traffic in GA4.
- Report monthly. Show the KPIs, the trend and the actions taken.
Note: AI answers vary between runs. One answer is an anecdote; a month of answers across a prompt set is data. Tools in our list of AI visibility tools repeat prompts automatically to smooth this out.
What is a good mention rate?
A good mention rate depends on your category and starting point. Use your competitors as the benchmark rather than a universal number. For our client Appsrow, tracking across 18 Webflow agencies over 90 days showed an 11% share of AI visibility, second among all agencies tracked. In a crowded category, moving from outside the top five to the top two is a stronger signal than any absolute percentage.
How should an AEO report look?
- A headline score: mention rate and citation share, this month vs last
- A prompt-by-engine grid: named and cited, named only, or missing
- Share of voice chart against competitors
- Top cited sources for your topics
- Description accuracy issues to fix
- AI referral sessions and conversions
- Actions completed and next month’s plan

Frequently asked questions
What is the most important AEO KPI?
Mention rate across your highest-value prompts. If you are not named, nothing else follows. Citation share is a close second because it drives clicks.
Can Google Search Console show AI Overviews performance?
Search Console includes clicks and impressions from AI features within overall web search data, but it does not break them out separately, so use a tracker for AI Overview citations.
How often should AEO KPIs be reported?
Monthly for most businesses, weekly during launches or in fast-moving categories.
How do I measure share of voice in AI answers?
Count all brand mentions across your prompt set, then divide your mentions by the total. Compare with each competitor’s share over time.
