Page Performance Evaluation agent

  • Updated

Page Performance Evaluation is an Optimizely Opal agent that runs a full Google Lighthouse audit on any live URL, covering Performance, Search Engine Optimization (SEO), Accessibility, and Best Practices. The agent then cross-references findings against a visual screenshot to pinpoint root causes and deliver specific, ranked fixes with real metric values.

  • Challenge – Teams struggle to diagnose why pages underperform. Audit tools surface scores but rarely connect them to root causes, and automated checks miss visual issues entirely.
  • Agent outcome – It produces a side-by-side view of Lighthouse scores and screenshot findings, identifies root causes, and ranks fixes by impact.
  • Value – The agent eliminates guesswork by pinpointing exactly what to fix and why. Teams prioritize the improvements with the most impact on page speed, search visibility, and user experience.
