# Performance Monitor Speed is a feature. Google search algorithms penalize slow websites, and users abandon them. The Performance Monitor section moves Signet beyond simple traffic counting and into the realm of infrastructure observability. We automatically collect and visualize the Core Web Vitals for every page view: * **Largest Contentful Paint (LCP):** Measures loading performance. * **First Input Delay (FID):** Measures interactivity and responsiveness. * **Cumulative Layout Shift (CLS):** Measures visual stability. The dashboard color-codes these metrics based on the official thresholds set by search engines (Good, Needs Improvement, Poor). This allows you to identify exactly which pages are dragging down your SEO score. You can filter performance data by country to see if your site is slow specifically for users in regions far from your origin servers, signaling a need for better CDN caching rules. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
