How to calculate conversion rate
Why conversion rate matters for Google Analytics users
Conversion rate is the metric that connects traffic to value. Driving more visitors to a site with a low conversion rate compounds waste rather than generating growth. Improving conversion rate multiplies the value of every acquisition channel without increasing spend.
Positioning conversion rate in your metric tree between traffic and revenue metrics reveals whether growth is constrained by acquisition (not enough visitors) or conversion (visitors not converting). This distinction fundamentally changes your investment strategy.
Understand and act on conversion rate with KPI Tree
KPI Tree syncs conversion rate data from your warehouse and tracks it per traffic source, landing page, device, and user segment. Position it as the pivotal metric in your acquisition-to-revenue tree.
Assign RACI ownership to your CRO specialist. Set alerts when conversion rates decline and track optimisation actions such as landing page tests, funnel improvements, and offer changes.

Goal Completion Rate
Web AnalyticsMetric Definition
Goal Completion Rate = (Goal Completions / Sessions) x 100
Goal completion rate measures the percentage of Google Analytics sessions that complete a predefined goal - such as reaching a destination page, meeting a session duration threshold, or triggering a specific event sequence. It quantifies how effectively your site achieves its defined business objectives.
Funnel Analysis
Web AnalyticsMetric Definition
Funnel analysis tracks user progression through defined conversion paths in Google Analytics - from initial landing through intermediate steps to final conversion. It identifies where users drop off at each stage, quantifying the conversion loss at every step and revealing the most impactful optimisation opportunities.
Bounce Rate
Web AnalyticsMetric Definition
Bounce Rate = (Single-Page Non-Engaged Sessions / Total Sessions) x 100
Bounce rate measures the percentage of Google Analytics sessions where the user viewed only a single page and triggered no additional events before leaving. In GA4, it is the inverse of engagement rate - a bounced session is one that was not engaged, meaning it lasted less than 10 seconds, had no conversion event, and had fewer than 2 page views.
Traffic Source Analysis
Web AnalyticsMetric Definition
Traffic source analysis examines how different acquisition channels - organic search, paid search, direct, referral, social, and email - contribute to sessions, engagement, and conversions in Google Analytics. It evaluates channel quality beyond volume by connecting source-level metrics to downstream outcomes.
Custom Event Conversion Rate
Web AnalyticsMetric Definition
Custom Event Conversion Rate = (Sessions with Custom Event / Total Sessions) x 100
Custom event conversion rate measures the percentage of sessions where users trigger a specific custom-defined event in GA4, such as video completions, file downloads, calculator interactions, or in-app actions. It extends standard conversion tracking to business-specific interactions that standard events do not cover.
