Prerequisites

  • Performance data from audit/crawl

QA focus

  • Metrics match lab data tolerance
  • Worst URLs ranked correctly

Overview

Performance Insights surfaces Core Web Vitals and related metrics from crawled pages so you can find slow URLs and confirm improvement after a fix.

What you get

  • Distribution of vitals and a ranked list of worst offenders
  • Per-URL vitals breakdown
  • A place to compare metrics after you re-crawl

How it works

  • Open Performance on the project once audit or crawl performance data exists
  • Sort the URL list and open a slow row for detail
  • Re-run the audit or crawl, then refresh to verify metric improvement (lab vs field can differ)

Common issues & false alarms

  • Lab vs field variance
