Conversion Rate

Conversion rate measures the percentage of Google Analytics sessions or users that complete a defined conversion event - such as a purchase, signup, form submission, or key feature interaction. It quantifies how effectively your website turns visitors into customers or leads.

How to calculate conversion rate

Conversion Rate = (Conversions / Sessions) x 100

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.

Funnel Analysis

Bounce Rate

Web Analytics

Metric 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.
