Google Core Web Vitals: A Complete Guide to Better SEO Ranking
Google is not only interested in keywords and backlinks; it also cares about how users experience your website. That’s why Core Web Vitals were introduced — a set of metrics that measure speed, interactivity, and visual stability.
In this post, you’ll learn:
- What Core Web Vitals are
- Why they matter for SEO and Google Discover
- How to test them
- Practical tips to improve your scores
What Are Core Web Vitals?
Core Web Vitals are three performance signals that reflect real-world user experience on your website.
1. Largest Contentful Paint (LCP)
- Measures how long it takes for the main content of a page to load.
- Good: under 2.5 seconds.
2. Interaction to Next Paint (INP)
- Replaced First Input Delay (FID).
- Measures how quickly your site responds to a user’s action (click, tap, scroll).
- Good: under 200ms.
3. Cumulative Layout Shift (CLS)
- Tracks how much your page layout shifts while loading.
- Good: under 0.1.
Why Are Core Web Vitals Important?
- SEO Ranking Factor: Google uses them to decide how user-friendly your site is.
- Better User Experience: A fast, stable site keeps visitors engaged.
- Higher Revenue: Faster pages lead to better ad viewability, more clicks, and higher conversions.
- Google Discover: Sites with poor vitals often struggle to appear in Discover.
