What are Key Performance Indicators (KPIs)? Analytics Definitions and Examples

Key Performance Indicators (KPIs) are quantifiable metrics used to evaluate the success of an organization, project, or specific activity in analytics. They provide a clear measure of performance relative to strategic objectives and help teams focus on what matters most. In digital analytics, KPIs might include metrics like conversion rate, bounce rate, or average session duration. By tracking KPIs with tools such as Plainsignal or Google Analytics 4 (GA4), businesses can monitor progress in real time and make data-driven decisions. Well-defined KPIs align with your business goals, are easy to understand, and can drive continuous improvement in marketing and product strategies. Selecting the right KPIs ensures that resources are allocated effectively and teams stay aligned on common objectives.
