Unlike traditional SEO — where rankings are relatively transparent — measuring Generative Engine Optimization success requires a different analytical lens. Key indicators include AI citation frequency (how often your brand is mentioned in AI-generated answers), referral traffic from AI-native platforms, brand mention volume across trusted domains, and share of voice in AI-generated industry conversations. Emerging GEO analytics tools are beginning to make this measurement more accessible, and forward-thinking agencies are already building custom dashboards to track it.
