01.Speed Directly Dictates Conversion Rates

Monolithic CMS setups carry heavy plugin payloads that delay first paint times. Google Ads rewards sites loading under 1 second with lower bid costs and higher ad placement.

Custom React and Next.js architectures pre-render pages at the edge, guaranteeing instant navigation transitions and zero UI layout shifts.

Key Tactical Takeaways

  • Ensure Core Web Vitals score above 90 on mobile devices.
  • Eliminate third-party render-blocking scripts with edge caching.
