Core Web Vitals Won't Save Bad Content (But They Can Break Good Content)

What CWV actually does

CWV is a tiebreaker. Two sites with equivalent content and authority — the faster one wins. Three sites with different content — content wins every time.

Thresholds that matter

LCP under 2.5s, INP under 200ms, CLS under 0.1. Beating these thresholds on 75% of real-user sessions is the bar. Average numbers lie — percentiles are what count.

The biggest wasted CWV effort

Over-optimizing desktop while mobile quietly fails. Most of your traffic is mobile. Most mobile devices are mid-tier. Test on a throttled Moto G, not your M2 MacBook.

When to stop optimizing

Once you pass thresholds on mobile, move on. Further gains rarely translate to ranking or conversion improvements. Double down on content instead.
