Core Web Vitals
Google's three page-experience measurements: loading speed, responsiveness, and visual stability.
What it means
Core Web Vitals are three specific measurements — how fast the main content loads, how quickly the page responds to the first interaction, and how much the layout shifts while loading. Google uses them as one input into search ranking.
Why it matters
A slow or jumpy page can quietly cost you both rankings and conversions, even when the content itself is good. They're one of the few technical SEO factors you can actually fix without rewriting content.

How do I know if my Core Web Vitals are bad?
Ask datanephew to check your PageSpeed Insights score for your key pages — it'll tell you which of the three measurements is falling short and on which pages.
Will fixing this actually improve my rankings?
It's one of many ranking factors, so it's not a guarantee on its own, but a page that's slow or jumpy is working against you on both search and the visitor who's already there.
