Core Web Vitals became an official Google ranking signal in 2021. Five years later, most SEOs still misunderstand what they actually do to rankings.
CWV are a tiebreaker, not a multiplier
Google has been consistent on this: Core Web Vitals are a lightweight ranking signal. They do not override relevance, authority, or content quality. If two pages are otherwise equal, the faster one wins.
The three metrics that matter
Largest Contentful Paint (LCP) — how long until the main content is visible. Target: under 2.5 seconds.
Interaction to Next Paint (INP) — how quickly the page responds after a user interaction. Target: under 200ms.
Cumulative Layout Shift (CLS) — how much elements move as the page loads. Target: under 0.1.
The honest summary
Pass the field data thresholds in Search Console, fix critical failures, then focus on content and links. That is where rankings are actually won.
