Real User Monitoring
A performance monitoring approach that captures and analyzes actual user experience metrics from real browser and device sessions, measuring page load times, interaction responsiveness, and visual stability as users experience them.
Real user monitoring (RUM) collects performance data from actual user sessions rather than simulated tests. It captures metrics like page load time, time to interactive, largest contentful paint, first input delay, and cumulative layout shift from real browsers in real network conditions, providing an authentic picture of the user experience.
For growth teams, performance directly impacts conversion. Research consistently shows that each additional second of load time decreases conversion rates. AI-powered RUM platforms automatically identify performance regressions, correlate performance with business metrics, and prioritize optimization opportunities based on user impact. Growth engineers should implement RUM across all critical user flows and establish performance budgets that define acceptable thresholds for key metrics. The most valuable RUM analysis segments performance by device type, network speed, and geographic region to identify specific user populations experiencing degraded performance. Teams should set up automated alerts for performance degradation and build dashboards that connect performance metrics to business outcomes like conversion rate and bounce rate, making the business case for performance investment clear and measurable.

Funnel Analysis
The process of tracking and measuring user progression through a defined sequence of steps toward a conversion goal, identifying where users drop off and quantifying the conversion rate between each stage.

The systematic measurement and analysis of the percentage of users who complete a desired action out of the total who had the opportunity, applied across multiple conversion points throughout the user journey.
Drop-Off Rate

Cohort Analysis
