Key takeaways

  • Rankings and traffic miss AI search; you need citation-level metrics.
  • Core KPIs: citation rate, share of voice, sentiment, and source attribution.
  • Track per model, ChatGPT, Perplexity, Gemini and AI Overviews behave differently.
  • Turn metrics into a source-influence roadmap, not just a dashboard.

Most teams still measure search with rankings and clicks, which say little about whether AI answers mention you. AI-search measurement needs its own KPIs. Here's the set that matters and how to operationalize it.

The core KPIs

MetricWhat it tells you
Citation rateHow often you're referenced for target questions
Share of voiceYour citations vs competitors on the same questions
SentimentWhether you're described positively, neutrally or poorly
Source attributionWhich sources drive your appearances
Answer accuracyWhether the model states your facts correctly
AI search KPIs

How to collect them

  • Define a question set that mirrors your funnel (awareness to decision).
  • Query each model on a schedule and log citations, mentions and sentiment.
  • Use a GEO tracking tool for scale, or a lightweight internal script to start.
  • Segment by model and geography, results diverge across both.

Frequently asked questions

What's a good AI citation rate?

There's no universal benchmark yet, measure relative to competitors and to your own trend. Rising share of voice on your priority questions is the signal that matters.

Do I need a paid tool to track AI search?

Not to start. A defined question set and scheduled manual or scripted checks give you a baseline; paid tools help scale coverage and history.

How often should I measure?

Monthly is a sensible cadence for most B2B teams, with spot checks after major content or PR pushes.
