Copilot surfaces Core Web Vitals data right next to the code that affects them. When you see a poor LCP score, you can immediately refactor the component causing layout shifts or optimize image loading — all without leaving your editor. This direct connection between performance metrics and source code accelerates optimization cycles.

  2. Review LCP, CLS, and INP results directly in your editor
  3. Ask: "Show me code changes to fix the LCP issue"
  4. Copilot can suggest specific code optimizations in your framework

Example Prompt
