Core Web Vitals: Why Speed Still Matters for SEO

Optic Rank Team·

Speed is a Ranking Factor


Google's Core Web Vitals — LCP, FID, and CLS — directly impact your search rankings. Poor performance means lower visibility.


The Three Pillars


  • LCP (Largest Contentful Paint) — How fast your main content loads. Aim for under 2.5 seconds.
  • FID (First Input Delay) — How responsive your page is. Aim for under 100ms.
  • CLS (Cumulative Layout Shift) — How stable your layout is. Aim for under 0.1.

    • How Optic Rank Helps
