Understanding Core Web Vitals
Three key metrics make up the Core Web Vitals: they measure aspects of the user experience. These are:
- Largest Contentful Paint (LCP): This measures the time it takes for a webpage’s main content to load. LCP measures loading performance and scoring good is when the largest visible thing, such as an image, video or chunk of text, loads within 2.5 seconds or less.
- First Input Delay (FID): Measures the time from the moment when the user clicks a link or taps a button until he starts to interact with the page. A good score is under 100 milliseconds which is a fast response time, and if a customer has to wait any longer than this, it is going to subtract from a positive experience.
- Cumulative Layout Shift (CLS): Measures the visual stability of a page. High CLS means that elements on the page jump around when loaded, which frustrates the user. The ideal is a score of less than 0.1.
Together, these metrics tell you all you need to know about how well a website ensures a smooth and pleasurable experience for its visitors. But if your website doesn’t adhere to the Google Core Web Vitals standards, you could see a hit on your SEO performance.
The Growing Importance of User Experience in SEO
Over the past few years, Google has become more and more obsessed with making sure each user action has the best user experience. Today, for the company’s search algorithms, the content and backlink profile are no longer the only ones being used to evaluate the site: the user interaction with it is also taken into account. It comes at a time, after all, when more people are accessing websites using mobile devices than ever before; and it fits in with Google’s ongoing positioning of mobile-first.
When a website is slow, looks ugly or is not responsive, users will bounce off your site and your bounce rate will increase and engagement levels will lower. Directly, these negative signals can impact your search rankings. However, websites that render a good user experience (fast page loads, smooth interaction, and stable layouts) are much more likely to keep users coming back, resulting in better rankings.
This is because not only are you optimizing your SEO, you are optimising your core web vitals which improves your website’s search engine performance, yet also improves the experience so that the user prefers to stay on your site longer, prefers your site engagement, would like to stay longer and convert more.
Why Core Web Vitals Should Be a Priority in 2025
1. Improved Search Rankings
2. Mobile-First Indexing
3. Enhanced User Engagement and Lower Bounce Rates
4. Increased Conversions and Revenue
5. The Growing Role of User Signals in SEO
How to Optimize for Core Web Vitals
1. Optimize Largest Contentful Paint (LCP):
- Serve images in modern format, e.g. WebP, and compress in native format.
- For non–critical images and videos, we’ll implement lazy loading so it doesn’t add much to our initial load time.
- Reduce server response time and get content efficiently.
- Reducing JavaScript and CSS files will allow rendering content on time.
2. Improve First Input Delay (FID):
- Use as little heavy (!) JavaScript files that can block the main thread and disrupt user interaction.
- Defer nonessential scripts and optimize to make the page interactive faster.
- Caching assets locally in the browser cache decreases the load time of assets when interacting with the app.
3. Reduce Cumulative Layout Shift (CLS):
- There should be defined size attributes for every media (images, videos, ads) so there shouldn’t be a layout shift.
- This gives you space to reserve for dynamic content such as ads or popups so that you don’t have to move everything around.
- Don’t inject content outside visible content boundaries, which may violate page layout.
4. Use Monitoring Tools:
- Using Google PageSpeed Insights, Lighthouse, and Google Search Console, regularly monitor your site’s Core Web Vitals and know what areas you can work on to improve.
The Future of Core Web Vitals
