What are Core Web Vitals?
Core Web Vitals are three metrics Google uses to evaluate the user experience quality of a page: how quickly the main content becomes visible, how quickly the page responds to the first input, and how much the layout shifts during loading. They are included as a ranking signal.
01 — Context
Core Web Vitals in Detail
Measurement is not done in the lab, but with real visitors — through the actual load times on their devices and connections. A page that works well on a fast office computer can perform significantly worse on an older phone on a mobile network.
The most common reason for poor values is not the text, but images at original size, too many embedded fonts, and third-party scripts — analytics, chat, maps, advertising. Each of these costs load time.
02 — Practice
What this means for small businesses
For small businesses, this is rarely the first lever, but a worthwhile one: Most local search queries come from mobile and on the go. A page that takes three seconds there loses visitors before they've read anything.
03 — Questions
Frequently asked questions
How do you check this?
Through Google Search Console or PageSpeed Insights. Both show the values from real visitors and identify the specific causes.
How strongly does this affect ranking?
Less strongly than content and relevance. With otherwise comparable results, though, it can tip the scale — and the effect on bounce rates is greater than the effect on ranking anyway.
