Why do you need teams ?
The teams function brings safety and confidentiality
If you are the owner of the site and do not have experience in analyzing and interpreting web statistics, you need the advice or help of a specialist. With teams you allow him to view the statistics and help you without having access to your account.
If you are a marketing agency and have a lot of clients, with the help of the teams section you can view the web traffic statistics of all the clients (who grant you access) without having to have access to the user account. This way you can analyze your client’s web traffic, make content improvements or establish a new marketing strategy that will bring better results for your clients.
