Measuring GEO ROI: a rigorous framework operators can defend

GEO without measurement becomes a content hobby. CFOs ask: what revenue moved? Operators need KPIs linking AI visibility to pipeline—not vanity "we published 40 AI blogs."

• Citation Rate (CR): % of tracked prompts where your domain appears in source lists, by engine and locale.
• Share of AI Voice (SOAV): your citations ÷ (yours + defined competitors) for category prompts.
• Source position: first-listed domains often earn disproportionate follow-up clicks in UIs that show sources.

Referral traffic from AI domains (where analytics allow). Branded search lift post-campaign. Direct landings on cited URLs.

Assisted conversions within 30-day windows. Holdout tests: URLs without GEO fixes vs treatment cohorts. Incrementality beats correlation.

90-day cohorts: 30-day baseline → implement fix pack → 60-day monitor. Minimum sample: 50 category prompts × 3 engines × weekly snapshots. Document prompt wording—small changes alter retrieval.

| Metric | Baseline | Week 12 | Δ | |--------|----------|---------|---| | Citation Rate | | | | | SOAV | | | | | Assisted revenue | | | |

Can GA4 track ChatGPT referrals? Partially—UTM hygiene and referral path analysis help; supplement with prompt monitoring.

What is a good CR for niche B2B? 5–15% on long-tail prompts can be meaningful; compare vs competitors, not generic benchmarks.

Should SEO and GEO owners share dashboards? Yes—shared URL inventory, split metrics.

Visora Monitor automates prompt snapshots; pair with /audit baselines so every CR delta maps to a shipped fix, not guesswork.
