If your site takes several seconds to become usable, you are likely to lose some visitors before they read the first line.
What are Core Web Vitals?
Core Web Vitals is a set of metrics Google uses to assess the real user experience on web pages. Even if the design is excellent, poor performance can affect user satisfaction and the site's visibility in search results. The core metrics are LCP, INP and CLS.
1. Largest Contentful Paint (LCP)
Measures how long the largest visible element on the page takes to render fully. It is often the main image, the page title, or the hero section. Target: under 2.5 seconds.
The most common causes:
- Large images.
- Slow hosting.
- Loading CSS or JavaScript before the content.
2. Interaction to Next Paint (INP)
Measures how quickly the site responds to the user's first interaction, such as tapping a button or opening a menu. Target: under 200ms.
Common causes:
- Heavy JavaScript.
- Unnecessary libraries.
- Running too many operations on the page.
3. Cumulative Layout Shift (CLS)
Measures the page's stability during load. If a button or image moves while reading, it raises CLS. Target: under 0.1.
Common causes:
- Images without width and height.
- Fonts loading late.
- Inserting new elements during load.
Why does speed affect business?
A faster site helps to:
- Reduce the visitor bounce rate.
- Increase contact requests.
- Improve the user experience.
- Support visibility in search results.
- Improve ad campaign performance.
Speed alone does not guarantee first place on Google, but it is an important part of the user experience that search engines rely on.
How do you improve your site's speed?
- Use WebP or AVIF images.
- Enable caching.
- Use a CDN.
- Remove unused JavaScript.
- Load fonts correctly.
- Compress CSS and JavaScript.
- Use lazy loading for images below the fold.
- Monitor performance after every update.
How do you measure performance?
The best tools:
- Google PageSpeed Insights.
- Google Search Console.
- Lighthouse.
- Chrome DevTools.
Do not rely on a single test; monitor real-user data (field data) when available.
Common mistakes
- Uploading images at a higher resolution than needed.
- Using too many plugins.
- Running unnecessary tracking scripts.
- Using too many fonts.
- Hosting that does not match the site's size.
Conclusion
A fast site does not only help search engines; it makes the site smoother to use and increases the chance a visitor stays and completes the action you want. Improving Core Web Vitals is not a one-time project, but part of the ongoing maintenance of any professional site.
