Previously, we displayed Performance Score, First Contentful Paint and Time to Interactive as default metrics in Calibre. This meant that you’d see those three metrics across Your Sites, Pulse, Pages Leaderboard, Pull Request Reviews and Insights reports. Now, Web Vitals (Largest Contentful Paint, Cumulative Layout Shift and Total Blocking Time) are the default metric set.
Web Vitals are now the default metric set, which means you will see them prominently displayed across all Calibre reports.
Web Vitals have been actively improved for several years and provide a holistic view on different aspects of user experience. Google also uses them as ranking signals for page experience. You can see Web Vitals across the previously mentioned areas. You can still customise metrics displayed in Pull Request Reviews, Pages Leaderboard and Pulse if you’d like to amend them. All measurements are colour-coded, so you know if they’re good (green), need improvement (orange) or poor (red).
In the future, we’ll be introducing more ways of view and metric customisation, as well as keeping track of KPIs.
