Executive brief

Key takeaways

  • Prioritize high-conversion routes.
  • Use field data (CrUX) rather than lab tests.
  • Extract a prioritized backlog to investigate later.

Deciding what to investigate first when a site shows anomalies can paralyze a team. A 30-minute triage does not solve the root cause but isolates the observed evidence into a clear plan.

What is triage and what is its method?

Triage identifies critical symptoms. The method samples high-value pages (homepage, checkout) using Google Search Console, DevTools, and field data (CrUX).

1. Technical verification (10 min)

Focus on server response and initial loading.

  • HTTP Codes: 5xx responses indicate service failure. 404 on critical routes drops conversion.
  • Error Console: Observe CORS failures or blocked scripts that break interactions in Chrome DevTools.

Limitation: Console errors do not always interrupt the journey for all users. Identify only critical ones.

2. Visibility (10 min)

Verify crawling for profitable URLs.

  • Sitemap and Coverage: In GSC, look for spikes in excluded pages.
  • Rendering and indexing: Validate canonical and robots tags.

3. Performance (10 min)

Evaluate UX bottlenecks at the 75th percentile.

  • Core Web Vitals: Look for INP (Interaction) and LCP (Rendering) anomalies with field data.
  • Blocking resources: Assess the size of scripts during main loading.

Compile the observations into an effort vs. impact matrix. Re-verify field metrics via Remountly on subsequent deploys to ensure the plan stabilized the environment.
