We use Google Analytics to check the daily activity of users on the platform. We generate reports on specific pages on their conversion rate. We view the demographic data as well as the real-time data on the site users. Also, we use it to attribute our landing page marketing by referring to the source URLs and campaign ID parameters.
Google Analytics has also helped with understanding the traffic distribution based on device and OS versions. Even though the data is sampled, it gives good info on the demographic details of the users.
