Core Web Vitals sound technical, but they measure something very concrete: whether your page feels fast and stable to an actual visitor.
Measures how long a visitor waits before the most important part of the page — usually a headline or hero image — is visible and usable.
Measures the delay between a visitor clicking or tapping something and the page actually responding. A slow response here feels broken, even if it eventually works.
Measures whether buttons, images, and text jump around as the page finishes loading — the frustrating experience of trying to tap a button that shifts right as you reach it.
All three directly affect whether a visitor trusts and stays on your page, independent of whatever ranking benefit Google assigns them.
