GEO has a measurement problem. AI tools don't expose impression counts, ranking positions, or click-through data the way Google does. The right response isn't to give up on measurement - it's to be honest about which metrics are real, which are vapour, and how to talk about progress.
Why are GEO metrics different from SEO?
With SEO you can measure rankings, traffic, click-through, and conversions in a tight loop. With GEO the user often never visits your site. The "view" happens inside the AI tool, where you have no instrumentation. This forces you to use proxies: prompt-based audits, server-log inspection, and traffic attribution from the small share of users who do click through.
Which metrics are worth tracking?
What is citation rate, and why does it matter?
Define a stable set of 10-20 buyer prompts. Each month, count how many of them mention your product at all. Citation rate is the percentage that do. It's simple, defensible, and trends cleanly over time. Pair it with the audit in the free GEO audit.
What is a position-weighted citation score?
A more nuanced version. Score first mentions 3 points, second mentions 2, later mentions 1, no mention 0. Sum across prompts. Captures prominence, not just presence.
How do you measure share of voice in AI?
For the same prompt set, count mentions of you and your top three competitors. Your share of voice is your mentions divided by the total. This is the metric founders most readily understand because it has a clean ceiling and floor.
How do you track sentiment and accuracy?
Skim the actual answers. Are AI tools describing you as you'd want? Naming the right category? Citing real customers and reviews? This is qualitative and you score it manually, but it catches the worst failure modes - the ones that destroy a sale even when you're mentioned.
How do you measure referral traffic from AI tools?
In GA4 (or your analytics of choice), build a segment for sessions referred from chatgpt.com, perplexity.ai, claude.ai and gemini.google.com. The absolute numbers will be small. The growth curve and the conversion rate of that traffic are what matter.
How do you track AI crawler hits?
Filter your server access logs for AI user agents (GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended, Applebot-Extended). Track total hits per week and which URLs are being fetched. Zero or declining crawler traffic is an early-warning signal.
Which metrics should I ignore?
- "AI ranking position" - AI answers aren't ranked lists. Order is fluid.
- "Estimated AI impressions" - mostly vapour. No tool has reliable input data.
- Backlink counts as a primary GEO metric - useful for SEO, weakly correlated with GEO citations.
How do I report GEO progress to a founder or exec?
A monthly one-pager with five things on it:
- Citation rate this month vs last month.
- Share of voice vs top 3 competitors.
- Three example answers (one good, one neutral, one bad).
- Referral traffic from AI tools (raw count + month-on-month change).
- The single biggest action you're shipping this month and why.
Resist the urge to over-engineer the report. GEO is a long compounding game. Honest, simple tracking beats a dashboard nobody trusts.
