Core Web Vitals
Core Web Vitals are Google's metrics for loading performance, interaction responsiveness and visual stability.
In detail
They describe experience, not relevance. Good scores will not rescue a page that answers the wrong question, but bad ones cost conversions on every visit.
The usual culprits are oversized images, blocking scripts and layout that shifts as elements load.
Example
A hero image served at full resolution delaying the largest content paint on mobile.
Why it matters
Speed and stability affect revenue directly, and are a tie-breaker between comparable pages.
Common mistakes
- Optimising lab scores while real mobile experience stays slow.
- Treating performance as a substitute for content work.
