The Basics of Core Web Vitals

Core Web Vitals are a set of performance indicators that measure the health of your website. They can tell you if your site is loading quickly and responsively. This means you’ll see an improvement in user experience and reduced bounce rates. You can use these metrics to ensure your site loads quickly on different devices, from desktop browsers to mobile phones (and everything in between).

What are Core Web Vitals?

Core Web Vitals (CWVs) are the most important page elements to load quickly. This is because they are the most likely to cause users to leave your site, and they’re also the ones that users will use more often. The concept of CWVs was developed to help companies make informed decisions about what aspects of their web design should be prioritized when optimizing performance.

There are three main types of Web Vitals: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). All three depend on how the page loads, including image size, page weight, and how fast it takes for elements to be displayed. By measuring these metrics, you can see which aspects of your site need improvement.

Why are they important?

Web vitals are essential because they are a key indicator of your website’s health and a significant factor in the overall user experience.

They’re important because they measure how well your site performs, which can help you identify areas where it underperforms or experiences issues.

It’s easy to see why CWVs are important. They allow companies to identify the most critical aspects of their site’s performance and ensure that those aspects receive proper attention. The most important thing to remember is that it’s not just about being fast. It’s about providing users with an experience that feels fluid, responsive, and engaging. Your website should have an overall speed score of 85% or higher when measured by Google Chrome.

How do I get them to load quickly?

You’ll want to use a CDN (Content Delivery Network) to serve your content from a server closer to the user. This will help speed up the site’s load time and decrease the amount of traffic on your own server. You can also use a caching plugin. It does some of the same things as a CDN but for smaller websites. Caching plugins store static files in memory or disk, so they don’t have to be constantly regenerated each time someone visits your site. This speeds up page loads significantly because only dynamic pages require new processing power from servers. In contrast, cached pages do not need any processing once they’ve been saved locally.

How do I know if I’m doing it right?

Once you’ve installed the initial set of core web vitals, it’s time to check in on your progress. To do this, you’ll want to use a performance monitoring tool like Pingdom or Google Analytics.

Pingdom will give you insights into your website speed and accessibility by testing how well your site loads for various devices. These tests help measure the reach of your content and whether or not users have any issues accessing it.

Google Analytics provides information on how many people visit your site every month (visitors) and which pages they spend the most time looking at (time on site). You should also look at which search engines send traffic to your website. This can help determine where else readers might find out about you or what keywords they use when searching online.


Core web vitals are vital for the health of your website. They control how your website looks and functions and how it performs on search engine rankings. Core web vitals include things like security, speed, and accessibility.
