Google cares about Core Web Vitals because they directly reflect how users experience a website. It's not just about content anymore — performance matters too. If your site is slow, unresponsive, or visually unstable, visitors notice. And now, so does Google.

What Are Core Web Vitals?

Core Web Vitals are part of Google’s Page Experience signals. They measure three key aspects of user experience:

• Largest Contentful Paint (LCP) – How fast the main content loads.
• First Input Delay (FID) – How responsive a page feels when someone tries to interact with it.
• Cumulative Layout Shift (CLS) – How stable the layout is as the page loads.

These metrics give you a clear picture of how real users are experiencing your site — and that’s why Google uses them in rankings.

How Do They Affect SEO?

Google officially includes Core Web Vitals as a ranking factor. That doesn’t mean they’re the most important thing, but they do matter — especially in competitive niches where every small edge counts.

Here’s what to keep in mind:

• Sites with good scores tend to rank better over time.
• Poor performance can hurt visibility even if content is strong.
• Mobile rankings are more sensitive since these metrics are mobile-first.

It’s not a sudden drop or boost — think of it like a quality signal among many others. But ignoring it makes your site weaker in the long run.

Why Google Emphasizes These Metrics

Google wants people to trust its search results. That means sending users to sites that work well and feel fast. Core Web Vitals help identify pages that load smoothly, respond quickly, and don’t shift around unexpectedly.

From a practical standpoint:

• Better performance often leads to lower bounce rates.
• Users stay longer and engage more on faster sites.
• It sets a standard for what “good” looks like across the web.

So while it’s partly about fairness, it’s also about making sure people have a decent experience after clicking a search result.

How to Improve Your Scores

Improving Core Web Vitals isn’t always easy, but it’s usually straightforward. Start by checking your current scores using tools like PageSpeed Insights or Google Search Console.

Some common fixes include:

• Optimize images and videos (they often delay LCP).
• Reduce JavaScript execution time (this helps FID).
• Always define image dimensions to prevent layout shifts (for CLS).

Also, don’t get stuck trying to hit perfect scores on every page. Focus on the worst-performing pages first, especially those driving the most traffic.

基本上就這些。 Core Web Vitals aren’t everything, but they’re a clear signal that performance matters for SEO.
