If you’ve spent any time trying to improve your website’s SEO, chances are you’ve come across the term Core Web Vitals. Maybe it came up during a site audit, or perhaps your developer mentioned it while talking about load speeds. Either way, it’s left many website owners wondering: does this actually affect where my site shows up in Google?
In this guide, we’ll break it down simply. We’ll explain what Core Web Vitals are, whether they’re really a ranking factor, and most importantly, what you can do about it.
What Are Core Web Vitals?
Core Web Vitals are a set of performance metrics created by Google to measure how users experience your website. They focus on three main things: loading speed, interactivity, and visual stability. In simpler terms, they tell Google how “comfortable” your site is for visitors.
Here are the three metrics:
- Largest Contentful Paint (LCP): This checks how quickly your main content loads. Under 2.5 seconds is the target.
- First Input Delay (FID): This measures how fast your site reacts when someone tries to click or interact. You want it to respond in under 100 milliseconds.
- Cumulative Layout Shift (CLS): This tracks whether your page elements jump around while loading. Keeping this stable is crucial for usability.
Think of Core Web Vitals as your website’s user-friendliness score.
Is Core Web Vitals a Ranking Factor?
Yes, Core Web Vitals are officially a Google ranking factor. They were included as part of the Page Experience update, which started rolling out in 2021. But before you panic, let’s put it in perspective.
Google has over 200 ranking signals, and Core Web Vitals is just one of them. It won’t outrank poor content with better loading speed, but it could help your page edge out a close competitor if all else is equal. So yes, it matters, but it isn’t everything.
How Much Do They Influence Rankings?
When people hear “ranking factor,” they sometimes assume it’s make-or-break. In reality, Core Web Vitals play a supporting role in SEO, rather than being the star of the show.
Here’s how they contribute:
- Improve User Retention: Visitors are more likely to stay and explore when your site is fast and stable.
- Lower Bounce Rate: If your page loads in under 3 seconds, people tend to stick around. That helps send positive signals to search engines.
- Support Competitive Rankings: When two websites offer similar value, performance can be the tie-breaker.
- Boost Trust and Professionalism: Fast and well-structured pages build credibility, especially for first-time visitors.
So while Core Web Vitals won’t fix bad content or poor SEO keyword relevance, they can absolutely boost a strong page.
How to Check Your Core Web Vitals
Knowing your site’s performance is the first step. Luckily, you don’t need to be a developer to understand the basics. Google provides several tools that give you detailed feedback.
PageSpeed Insights
This free tool is perhaps the easiest place to start. Enter your URL, and it gives a performance score out of 100. It also shows how your Core Web Vitals perform on both mobile and desktop. You’ll get real suggestions to fix issues too.
Google Search Console
If your site is verified in Search Console, head to the “Core Web Vitals” section under the Experience tab. This shows which URLs pass or fail the metrics. It categorises issues by type, which helps prioritise your next steps.
Lighthouse in Chrome DevTools
Lighthouse is built into Chrome and can be accessed by right-clicking on a page, selecting “Inspect,” and navigating to the “Lighthouse” tab. This provides a deep audit of performance, accessibility, and more. It’s ideal for developers or tech-savvy site owners.
Web.dev Measure
This is another tool from Google that checks your site’s performance and gives practical suggestions. It’s especially helpful if you’re trying to improve mobile performance, which Google prioritises.
GTmetrix
Although not from Google, GTmetrix gives valuable insight into speed and performance. It visualises your site’s load process, helping identify which elements slow things down. This complements your Core Web Vitals work.
Tips to Improve Core Web Vitals
Once you’ve identified weak points, the next step is action. The fixes don’t always require heavy coding or redesigns. Here are a few changes that can go a long way:
- Optimise Images: Large images are often the main culprit behind slow loading. Compress them, use proper dimensions, and serve them in modern formats like WebP.
- Minimise JavaScript and CSS: Scripts can delay interactivity. Reduce unnecessary ones and defer loading when possible. Tools like WP Rocket or Autoptimize can help, especially on WordPress.
- Enable Lazy Loading: This delays the loading of off-screen images until they’re needed. It shortens the initial load time and improves the user experience.
- Upgrade Hosting and Use a CDN: Cheap shared hosting may slow you down. Using a better provider and a content delivery network can speed up delivery across regions.
These changes can have a massive effect on your LCP and FID scores. They also help make your site feel cleaner and more professional, giving users (and search engines) more reasons to trust it.
Conclusion On Core Web Vitals As A Ranking Factor
So, is Core Web Vitals a ranking factor? Yes. But should it be your main SEO focus? Not quite. Think of it as a support beam that helps hold up your website’s visibility, but it can’t do the job alone.
Improving Core Web Vitals is worth your time because it makes your site better for both users and search engines. While chasing keyword search volume or publishing evergreen content will help with visibility, performance ensures that visitors stick around to enjoy what you’ve built.
