Speed Score: Classifies a page as fast, average, or slow using two metrics: First Content Painted (FCP) and DOM Content Loaded (DCL). A page is considered fast if both metrics are in the top third of their category.
Optimization Score: Ranks the page as good, medium, or poor based on performance headroom.
Page load distribution: Chrome classifies a page as armenia number data (fastest third), average (middle third), or slow (bottom third) compared to all FCP and DCL events in the User Experience Report.
Page statistics: Can indicate whether a page could be faster if the developer modifies the page's appearance and functionality.
Optimization suggestions: A list of best practices that can be applied to a page.



Google's Lighthouse is a handy tool for mobile performance, accessibility, and progressive web apps audits. It provides a variety of useful metrics that can be used to measure page performance on mobile devices, such as:

The first meaningful paint that measures when the main content of a page is visible.
Interactive time is the point at which the page is ready for interaction with the user.
Speed Index measures how quickly a page loads.
Both tools provide recommendations to help improve any reported site performance issues.
