Insights

To analyze your site, navigate to your published site, load the page, and then launch the Page Optimizer. Community Page Optimizer Insights tab

The Insights tab (1) evaluates your page based on best practices for web applications developed using the Lightning framework. This tab displays an overall performance score (3) along with individual scores (5) for various analysis rules. To view details and suggested actions, click each rule. For more room to work, click Popout (2).

The Insights tab is conservative in providing recommendations. For further insights, consider reviewing the raw data presented on the Waterfall, Timeline, Charts, Cost, and Actions tabs.

To remove collected metrics, click Clear (4). Perform some user actions on the page to collect new metrics, and then reopen the Page Optimizer. For example, to gather performance metrics for liking a feed item, clear performance metrics, click Like, and reopen the Page Optimizer.
