Introduction
In 2025, Google continues to emphasize user experience as a critical ranking factor, and the latest Core Web Vitals update is proof of that. If your website isn’t meeting the performance benchmarks set by Google, you’re likely losing traffic, visibility, and conversions. In this blog post, we’ll break down what Core Web Vitals are, the 2025 updates, how they impact SEO, and how businesses can prepare and optimize effectively.
What Are Core Web Vitals?
Core Web Vitals are a set of user-centric metrics developed by Google to measure loading speed, interactivity, and visual stability. These are part of Google’s broader Page Experience signals.
As of 2025, the primary Core Web Vitals are:
- Largest Contentful Paint (LCP) – Measures load speed. Should occur within 2.5 seconds.
- Interaction to Next Paint (INP) (replacing FID) – Measures overall responsiveness. Should be below 200ms.
- Cumulative Layout Shift (CLS) – Measures visual stability. Score should be below 0.1.
What Changed in the 2025 Core Web Vitals Update?
Google introduced some important refinements this year:
INP Replaces FID
- First Input Delay (FID) only measured the delay of the first interaction.
- Interaction to Next Paint (INP) offers a more complete picture by measuring all interactions across the session.
Mobile Performance Now Heavily Weighted
- Google now prioritizes mobile CWV scores over desktop in ranking algorithms.
- Sites that perform well on mobile see better results.
Thresholds Are More Strict
- To be considered “Good”, your site must pass all three metrics on 75% of page loads.
Core Web Vitals Are a Tie-Breaker
- When content quality is equal, Core Web Vitals can determine which site ranks higher.
Why Core Web Vitals Matter for SEO
- They directly influence Google rankings.
- They impact user retention and conversion — slow or unstable sites drive users away.
- Google has confirmed that page experience is a part of the ranking algorithm.
According to a study by Search Engine Journal, pages that meet CWV benchmarks are 24% more likely to rank in the top 10 of search results.
