The Lifetime Value report lets you understand how valuable different users are to your business based on lifetime performance across multiple sessions.
For example, you can see lifetime value for users you acquired through email or paid search. With that information in hand, you can determine a profitable allocation of marketing resources to the acquisition of those users.
You can also compare the lifetime values of users acquired through different methods. For example, you can compare users acquired through organic search and users acquired through social, or compare social to email, to see which method brings the higher-value users.
