The key is to diagnose by template. A homepage, blog post, product page, and category page often have different bottlenecks. Field data matters more than one perfect Lighthouse run.
- LCP: optimize the largest visible element
- INP: reduce main-thread blocking
- CLS: reserve layout space
- Compare lab and field data
- Fix template-level problems
INP Troubleshooting
INP often comes from heavy JavaScript, slow event handlers, third-party scripts, filters, menus, forms, and cookie banners. Record interactions in Chrome DevTools and look for long tasks blocking the main thread.
For ad-heavy pages, reserve ad space, lazy-load lower placements carefully, and measure whether ad scripts are hurting interaction responsiveness.

- Heavy third-party scripts
- Cookie banner shifts
- Ad layout jumps
- Hydration delays
