Original: How I Approach WordPress Core Web Vitals Before Rebuilding Anything

Short summary

WordPress sites rarely need a full rebuild—instead, systematically audit Core Web Vitals to diagnose root causes: LCP delays from images or render-blocking CSS, INP problems from heavy JavaScript, CLS issues from layout shifts. Measure before and after each fix in priority order, and only consider rebuilding if architecture proves to be the culprit.

  • •Diagnose Core Web Vitals (LCP, INP, CLS) before rebuilding; most issues trace to images, CSS, plugins, or hosting—not architecture
  • •Optimize images and LCP delivery, reduce unnecessary JavaScript, and stabilize layout shifts through methodical measurement and testing
  • •Reserve space, preload critical resources, and defer non-essential scripts; measure impact of each change rather than installing multiple plugins blindly

Generated with AI, which can make mistakes.
