What Are Core Web Vitals?

Before diving into the new changes, let’s quickly recap what Core Web Vitals are. These are a set of metrics Google uses to measure real-world user experience on your site.

The three main Core Web Vitals are:

• Largest Contentful Paint (LCP): How quickly the main content loads.
• Interaction to Next Paint (INP): How fast the page responds to user interactions (replacing FID).
• Cumulative Layout Shift (CLS): How stable your layout is while the page loads.

Core Web Vitals 2.0 and What’s New in 2025

Google introduced Core Web Vitals 2.0 to better reflect how people actually experience websites. One of the biggest changes is the replacement of First Input Delay (FID) with Interaction to Next Paint (INP).

While FID only measured the first interaction, INP captures the overall responsiveness of your website. That means it’s now more about how your site behaves throughout a user’s visit, not just during the first click.

Core Web Vitals Test: How to Check Your Site’s Performance

If you want to know how your site performs, you can easily run a Core Web Vitals test using Google tools like:

• PageSpeed Insights
• Search Console (Core Web Vitals Report)
• Lighthouse

These tools show real data on how fast your pages load, respond, and stabilize. They also suggest improvements like compressing images, removing unused JavaScript, or enabling lazy loading.

SEO Core Web Vitals: Why They Matter

You might be thinking why does Google care so much about these numbers? The answer is simple: user experience equals better SEO.

When a page loads faster, users stay longer and bounce less. This sends a positive signal to Google that your site provides value. That’s why SEO Core Web Vitals are now part of the ranking system.

A page that performs well across Core Web Vitals metrics is more likely to appear higher in search results. In competitive niches, this small edge can make a big difference.

Core Web Vitals Impact on SEO

Let’s talk about the real-world Core Web Vitals impact on SEO. Many site owners noticed that after the first Core Web Vitals update, pages that offered a smoother browsing experience started performing better.

In 2025, this effect is even stronger. Google’s ranking algorithm now weighs site performance more deeply than before.

Here’s what this means:

• Good Core Web Vitals scores can boost visibility and improve click-through rates.
• Poor scores can lead to ranking drops, even if your content is excellent.
• Mobile performance matters more than ever since most users now visit from phones.

Does Core Web Vitals Affect SEO Directly?

Yes and Google has confirmed it. If you’re asking, “Does Core Web Vitals affect SEO?” the short answer is absolutely.

While it’s not the only ranking factor, it’s an important one. Think of it this way: even if your content is informative and well-written, users won’t stay if your site takes forever to load or keeps shifting while they read.

How to Improve Your Core Web Vitals in 2025

If you’re serious about improving site performance, start with these steps:

1. Optimize images and videos – Use modern formats like WebP and ensure proper compression.

3. Use a content delivery network (CDN) – It helps serve your site faster across different regions.
