Core Web Vitals — is a set of metrics from Google that determine how fast, convenient, and stable your website is for users. In 2025, the standards for these metrics changed, and now they have an even greater impact on SEO and search rankings. In this article, we'll take a look at what's new in Core Web Vitals and how to adapt your website to the updates.
What are Core Web Vitals?
Core Web Vitals are three key metrics that evaluate user experience:
- LCP (Largest Contentful Paint) — the time it takes to display the main content of the page.
- INP (Interaction to Next Paint) — the speed of the site's response to user actions (a new metric that replaced FID in 2025).
- CLS (Cumulative Layout Shift) — stability of the page layout during loading.
Google uses these metrics to determine how fast, user-friendly, and stable a website is for visitors.
What changed in 2025
- Replacing FID with INP
Indicator INP now more accurately measures user interaction with the site, taking into account all clicks, button presses, and actions, not just the first reaction. - Strengthening the impact on SEO
Google has stated that Core Web Vitals carry more weight in ranking algorithms — slow websites lose positions even with high-quality content. - New recommendations for mobile devices
The mobile version of the website has become a priority for metric evaluation. Optimizing images, fonts, and responsive design is critically important.
How to improve Core Web Vitals metrics
- Optimize images
Use modern formats (WebP, AVIF) and automatic compression without loss of quality. - Configure caching
Cache helps speed up page reloads, reducing the load on the server. - Minimize JavaScript and CSS
Remove unnecessary scripts, reduce file size, and defer loading non-essential elements. - Improve the mobile version
The website should display correctly on all screens, without shifts or delays when clicking. - Use a CDN
Content delivery networks (CDNs) speed up website performance for users in different regions.
