Build and apply segmentation models and cohort analyses to uncover behavioral patterns, lifecycle trends, and funnel opportunities.
Analyze organic search and AEO signals as modeling inputs to inform content strategy and improve discoverability.
Partner with analytics engineers to productionize models and move insights from notebook to pipeline.
