Google Lighthouse is a free and open-source tool that provides a snapshot of your website's performance and search engine optimization (SEO). It can be integrated into your New Relic One dashboard to track metrics continuously and receive alerts if performance metrics worsen. Using Google Lighthouse, you can analyze site performance, accessibility, and SEO, and gain insights into how quickly your site loads and how long it takes for users to see content. By adding Lighthouse data to your New Relic One dashboard, you can get baseline metrics that aren't affected by real-world conditions, making your dashboard more versatile and leading to new insights into your site's performance. You can also set up alerts on incoming data from Google Lighthouse to monitor performance and receive notifications when issues arise. Integrating Lighthouse with New Relic One allows for easy visualization of metrics and enables you to focus on important metrics like accessibility and SEO, while gaining a better understanding of how your site is performing.
