In order to collect and see all the data that’s important to you in a meaningful way, it is necessary to structure your GA account properly, using different views and filters for segmentation, measuring goals to assess performance, and make all other necessary configurations. All of these actions are done through the Admin section of Google Analytics (some advanced implementations may also require certain code adjustments to GA script).
Google has recently made a complete redesign to the admin interface, aimed at making account administration both simpler and faster. In particular, all the settings (account settings, property settings, profile / view settings) are now directly accessible from one main page, so they’re easier to find and faster to navigate through.
Watch out for these changes in your GA Admin interface, as they are rolling out to all users during the coming weeks.
