RUM (Real User Monitoring)
Sitecheck Team
Performance data collected from real users in production.
RUM (Real User Monitoring) collects performance data from actual users in production. It reflects real networks, devices, and user behavior, and is used to understand true user experience.
Why it matters: Field data is what search engines and users actually experience, and it can differ from lab tests.
Quick tips:
- Sample traffic to avoid excessive overhead.
- Segment by device class and region to find bottlenecks.
- Combine with lab tests for root-cause analysis.
