Measuring Performance with Core Web Vitals
Website speed is one of the most important factors when it comes to creating a seamless user experience. We need to know the metrics, tools, and best practices that measure and enhance speed. It’s this understanding that will allow us to perform at our highest level. Here’s how we see it in digestible chunks.
- Use Core Web Vitals Metrics
- Test with Performance Tools
- The Industry Standard Tools
- Analyze Page Speed Across Devices
- Compare Performance in Different Locations

Addressing Content Loading Shifts (CLS issues)
Content loading shifts, known as layout shift during page load, negatively impact user experiences and erode website performance. Addressing these issues is extremely important for improving content usability and protecting against disruptive content loading shifts.
- Cumulative Layout Shift: visual stability as content loads
- Minimize Layout Changes During Loading
- Optimize Fonts and Images for Stability
Improving Longest Contentful Paint (LCP issues)
Making LCP as good as it can be is at the heart of providing a smooth and rewarding experience while users browse. LCP stands for longest contentful paint, and it’s a measure of how long it takes the largest content you see to load. This is often a main headline, hero image, or video that sits above the fold.
So, a good LCP score—2.5 seconds or less ideally—means you have quick load times for users, which is crucial for both user satisfaction and engagement. As you know, poor LCP scores usually result in higher bounce rates, particularly if the delay causes frustration to the user.
Fixing JavaScript Performance Issues (Scripts)
JavaScript is a vital part of modern web development, but when used incorrectly or unnecessarily, it can contribute to slower websites. Unoptimized scripts can severely hinder download speed, rendering and even affect the client device such as CPU and battery consumption. Fixing these issues directly improves load times and user experience before users ever experience negative effects.
Enhancing Media Loading Speed
These media files are usually the biggest elements on any given website, greatly impacting loading speed. Each additional second of loading time annoys users. Research shows that many of them are not willing to wait at all.
50% of them want pages to load in under three seconds. To fix this, optimizing media is critical to achieving a faster performance while maintaining quality.
Maintaining Consistent Performance
Remember, speed is important. Research shows that almost half of your users will abandon a site if it takes more than two seconds to load. If it takes more than three seconds, 40% of them will abandon the site entirely.
In the end, thoughtful approaches make it possible to continue delivering effective strategies that users want to stay engaged and happy.
