Demystifying Lighthouse, CrUX, and Core Web Vitals
Core Web Vitals Tools: An Overview
To make real improvements to Core Web Vitals, you need tools that not only measure performance but also provide actionable insights and track progress over time. Google offers several tools to help you tackle this challenge effectively.
Google PageSpeed Insights
Google PageSpeed Insights breaks down Core Web Vitals scores and offers practical recommendations to improve them. Here’s what it does best:
- Analyzes performance for both mobile and desktop platforms.
- Uses real-world user data for high-traffic pages.
- Provides targeted suggestions to boost performance.
Lighthouse and Chrome DevTools
Lighthouse and Chrome DevTools are essential for performance testing and debugging. Lighthouse, built into Chrome DevTools, simulates different devices and network conditions to identify potential issues before they impact users.
| Feature | Lighthouse | Chrome DevTools |
|---|---|---|
| Testing Environment | Lab Data | Real-Time Monitoring |
| Performance Metrics | Detailed Audit Reports | Instant Performance Insights |
| Key Strengths | In-depth audits and suggestions | Quick debugging feedback |
Core Web Vitals Report in Search Console
The Core Web Vitals Report in Search Console provides a bird’s-eye view of your website’s performance. It tracks key metrics like LCP, INP, and CLS across your site, helping you pinpoint and prioritize problem areas.
For advanced monitoring, tools like DebugBear and New Relic go a step further, offering continuous tracking and real-user data analysis. These options can enhance your ability to fine-tune performance.
Armed with these tools, you’re ready to start testing and optimizing your website’s Core Web Vitals one step at a time.
How to Use Core Web Vitals Tools
Core Web Vitals tools help pinpoint performance issues and offer insights for improving your site’s user experience. Here’s how to make the most of them.
Running Tests with Google PageSpeed Insights
Start by entering your website’s URL into Google PageSpeed Insights. This tool evaluates both mobile and desktop performance. Pay close attention to the performance score, Core Web Vitals metrics like LCP (Largest Contentful Paint), INP (Interaction to Next Paint), and CLS (Cumulative Layout Shift). Check the ‘Opportunities’ section for practical suggestions, such as compressing images or reducing server response times.
Performing Audits with Lighthouse
To run a Lighthouse audit, open Chrome DevTools (press F12 or right-click and select Inspect), navigate to the Lighthouse tab, and start the audit. For more accurate results, use incognito mode. Lighthouse simulates various devices and network speeds, delivering a deep dive into your site’s performance.
| Audit Category | Key Focus Areas | Why It’s Important |
|---|---|---|
| Performance | Loading times and optimization tips | Helps identify speed-related issues |
| Best Practices | Modern web development standards | Ensures your site is technically sound |
| Accessibility | WCAG compliance | Enhances usability for all users |
Tracking Issues in Search Console
Visit Search Console and navigate to the Core Web Vitals report under the ‘Experience’ section. This report shows performance trends over the last 90 days and groups similar issues, making it easier to address the most pressing problems first. Keep an eye on the ‘Fixed’ validation status to confirm improvements.
After diagnosing issues with these tools, the next step is applying targeted fixes to boost your Core Web Vitals scores.

Fixing Core Web Vitals Issues
Here’s how you can address LCP, INP, and CLS issues with targeted solutions.
Improving Largest Contentful Paint (LCP)
Speeding up LCP often comes down to optimizing how content is delivered and displayed. Use a CDN to serve assets faster, and compress images with tools like TinyPNG or ShortPixel to cut file sizes significantly. For fonts and videos, modern formats and preloading can make a big difference.
| Media Type | Optimization Technique | Impact on Performance |
|---|---|---|
| Images | Compression + WebP format | Reduces file size by 40-80% |
| Videos | WebM/H.264 encoding | Speeds up loading by 30-50% |
| Web Fonts | Font CDN + preloading | Improves LCP by 20-35% |
Reducing Input Delays for Interaction to Next Paint (INP)
To improve INP, focus on reducing JavaScript execution time. Implement code splitting to ensure only essential scripts load for each page. This approach minimizes delays and makes your site more responsive. For example, prioritize LCP improvements on e-commerce pages and INP enhancements for interactive platforms.
Preventing Layout Shifts for Cumulative Layout Shift (CLS)
Avoiding layout shifts is all about maintaining a stable visual experience. Here are some practical tips:
- Reserve Space for Images and Dynamic Content: Specify exact dimensions in your CSS to prevent unexpected shifts.
- Stabilize Font Loading: Use system fonts or preload custom fonts to ensure your text doesn’t jump around.
- Preallocate Space for Popups or Ads: Set aside space for dynamic elements to keep your layout steady.
These steps not only improve CLS but also create a smoother user experience overall.
Maintaining Good Core Web Vitals Scores
To keep your Core Web Vitals scores in check, use tools like PageSpeed Insights and Search Console to monitor performance regularly. It’s a good idea to review performance weekly, especially during peak traffic periods, to catch and address any issues early.
| Monitoring Frequency | Tool | Key Metrics to Track |
|---|---|---|
| Weekly | PageSpeed Insights | LCP, INP, CLS scores |
| Daily | Search Console | Performance trends, issues |
| After Updates | Lighthouse | Technical audit results |
These tools help you stay on top of your website’s performance, but monitoring alone isn’t enough. Integrating Core Web Vitals into your development workflow can make a big difference in maintaining long-term performance.
Including Core Web Vitals in Development
Add automated Core Web Vitals checks to your continuous integration pipeline. This way, potential problems can be identified and resolved before they make it to production. Developers can also use Chrome DevTools during the development process to pinpoint bottlenecks and ensure smooth performance.
Keeping Up with Updates
Stay informed by following trusted sources like the Google Webmaster Central Blog for the latest updates and best practices. Here’s a key stat to remember: a 1-second delay in page load time can reduce conversions by 7% [1].
To prevent performance issues, consider setting up performance budgets for your development team. These budgets set clear limits for metrics like file sizes, load times, and Core Web Vitals scores. If thresholds are exceeded, automated alerts can notify your team to investigate and resolve the problem quickly.
