Your 10-Step Roadmap
to Lighthouse Score 100

What is the Lighthouse performance score?

The Lighthouse Performance Score is a metric used to evaluate the performance of a website or web application. It is generated by the Google Lighthouse Audit, a tool that provides a comprehensive analysis of various performance metrics.

The Lighthouse Performance Score takes into account factors such as page load speed, responsiveness, and overall user experience. It assesses performance based on core web vitals, including Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift.

Lighthouse reports generated by the Google Lighthouse Audit provide detailed insight into a site's performance and highlight areas for improvement. By using Lighthouse and Pagespeed Insights, site owners can optimize their sites to improve the user experience and increase performance.

In essence, the Lighthouse Performance Score serves as a benchmark for evaluating a site's efficiency and effectiveness, providing valuable data for improving site performance and usability.

Why is Lighthouse score important?

The Google Lighthouse Score is important for both website owners and website developers because it helps them to evaluate the performance and user experience of a website.

• Insightful metrics: The Lighthouse Score generated by the Google Lighthouse Audit provides valuable insight into a variety of performance metrics, including core web metrics such as Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift. These metrics provide a comprehensive view of how well a site is performing in terms of speed, responsiveness, and visual stability.

• User Experience Optimization: A high Lighthouse Score indicates that a site delivers a superior user experience. Sites with fast load times, smooth navigation, and optimized content tend to receive higher scores, increasing user satisfaction and engagement.

• SEO Impact: Google considers user experience a critical factor in search engine rankings. Sites with higher Lighthouse Scores are likely to rank higher in search results, resulting in increased visibility and organic traffic.

Performance Benchmarking: The Lighthouse Score serves as a benchmark for evaluating and comparing the performance of different Web sites. It helps identify areas for improvement and guides developers in implementing optimizations to improve overall performance.

In essence, the Lighthouse Score is important because it not only reflects the quality of a website's user experience, but also influences its visibility in search engine results. By striving for a high Lighthouse Score, site owners can ensure that their sites deliver optimal performance and user satisfaction, resulting in increased traffic and engagement.

How to check Lighthouse score?

To check your site's Lighthouse Score, you can use Google's tools: Lighthouse Reports and Pagespeed Insights.

Lighthouse Reports:

Access Lighthouse Reports directly from Google Chrome's Developer Tools. Simply right-click on your web page, select "Inspect", and then navigate to the "Audits" tab. From there, you can run a Lighthouse Audit, which will generate a comprehensive report detailing various performance metrics along with your Google Lighthouse Score.

Alternatively, you can use the standalone Lighthouse tool by installing it via npm or using it as a Chrome extension. This tool allows you to generate detailed reports for any web page URL.

Pagespeed Insights:

Pagespeed Insights is another invaluable tool provided by Google. Simply visit the Pagespeed Insights website, enter your website's URL, and click "Analyze. In addition to providing performance metrics, Pagespeed Insights will also display your Google Lighthouse Score, providing valuable insight into your website's performance.

By using these tools, you can regularly monitor your site's performance, identify areas for improvement, and work to improve your Google Lighthouse Score for a better user experience and overall performance.

What is a good Lighthouse score?

Lighthouse Reports evaluate several aspects of your site, including performance, accessibility, and best practices, and assign a score on a scale of 0 to 100. A score closer to 100 indicates superior performance and user experience.

A good Lighthouse score is typically between 90 and 100. A score above 90 indicates that your site loads quickly, is highly responsive, and meets accessibility standards; scores between 50 and 89 indicate need for improvement; and scores below 49 are considered poor.

Performance metrics such as the Speed Index, which measures how quickly content is visually displayed when a website loads, contribute significantly to the Lighthouse Score. Sites with lower Speed Index scores tend to perform better in Lighthouse evaluations.

Ultimately, striving for a Lighthouse Score of 90 or higher ensures that your site delivers an optimal user experience, which promotes visitor engagement and satisfaction. Regularly monitoring Lighthouse reports and implementing optimizations can help maintain or improve your site's performance over time.
