A Page is where you can arrange multiple Snapshots and add context in a single view. It's a bit like a single slide where you can add Snapshots and text. The most common way people use Pages is to build mini "dashboards" with multiple Snapshots.
You can also add Snapshots to Google slides and embed them in other apps, like Notion and Confluence.
An example of multiple Snapshots on a Page in Plus
Open the Snapshot picker from the top of the Pages toolbar. From there, search for the Snapshot you want to use and click it to place it on the Page.
