 An Event Counter trait stores a count of an **event** over a period of time. For example, you can create a trait called `number_logins_90_days` based on a `User Logged In` event. You can also use event properties to only specific types of events.

-## Connecting your Computed Trait to a Destination
+## Connecting your computed trait to a destination
 
 Segment sends user-level computed Traits to destinations using the [Identify call](/docs/connections/spec/identify/) for user traits, or using the [Track call](/docs/connections/spec/track/) for event properties. Segment includes the trait value and property in the Identify and Track calls.
 
 For example, the name of a computed trait is added to the user profile as a trait, and the trait's value is set to the value of the computed trait. Segment sends an Identify or Track call when the trait is computed, depending on the destination configuration. If a computed trait counts the number of times a user visits your pricing page, and the user visits your pricing page five times, Segment sends an Identify call with the property `pricing_page_visits: 5`.

-For account-level computed traits, you have the option to send either a [Group](/docs/connections/spec/group/) call and/or [Identify](/docs/connections/spec/identify/) call. Group calls will send one event per account, whereas Identify calls will send an Identify call for each user in the account. This means that even if a user hasn't performed an event, Segment will still set the account-level computed trait on that user. Because most marketing tools are still based at the user level, it is often important to map this account-level trait onto each user within an account. See [Account-level Audiences](/docs/engage/audiences/account-audiences) for more information.
