Custom dimensions and metrics allow you to segment GA4 reports by data points unique to your business — subscription plan, product category, user role, A/B test variant, page template, or any other dimension that matters to your analysis. We design and implement the data layer variables that carry this data, create the corresponding custom dimensions in GA4, and configure GTM to pass them with every event so your reports can be segmented exactly as your business needs.
