Slow load times, UI lag, and general performance issues can severely impact conversion. Noibu integrates Core Web Vitals into session recordings, enabling engineering and product teams to pinpoint where and when performance drops occur. By analyzing these replays, teams can validate reported issues and prioritize improvements that enhance overall site responsiveness.
Workflow
- Open Sessions page and filter by performance-affected URL. Add a filter for "Poor" or "Needs Improvement" Web Vitals. For example, you might filter to “URL contains outerwear“ and “CLS = poor“ within a given date range to find a list of session recordings that show how a low CLS score impacted your customer.
- Watch session replays to understand user behavior during degraded performance.
-
Enable Web Vitals in the timeline to pinpoint performance dips.
- Examine each Poor or Improvable entry to see the value. This should give you an idea of how much the performance issue is impacting the shopper experience, and how much opportunity you have to optimize the page's performance. Additionally, note what's happening in the session recording when the poor web vital score appears. This can give you insight into what the shopper was doing when the performance issue arose.
Common Filters
- Web Vital score (LCP, CLS, INP)
- Date/Time
- URL
- Session Symptoms
Next Steps
Prioritizing and Sharing Sessions
As you review a session replay, you may discover details or insights that should be shared with other team members for more context, prioritization, and/or performance optimization. Learn more about gauging the impact of a session, and how to share or action it.
Analyzing broader performance trends
Session replays are especially useful for understanding how individual users are impacted by poor performance. However, if multiple sessions exhibit similar issues, teams should use Noibu's Performance Monitoring feature to identify broader trends across the site. Performance Monitoring aggregates Core Web Vitals (LCP, INP, CLS) across thousands of real user sessions, providing actionable insights and highlighting top pages with performance degradation that require attention.
