How to calculate goal completion rate
Why goal completion rate matters for Google Analytics users
Goals represent the specific outcomes your website exists to achieve. Unlike generic engagement metrics, goal completion rate directly measures whether your site fulfils its purpose for each visitor. A site with strong engagement but weak goal completion has an experience that attracts attention without guiding it toward value.
Positioning goal completion in your metric tree connects site objectives to downstream business metrics. When goal completion drops, the tree reveals which traffic sources, landing pages, or funnel steps are responsible.
