Finally, define any [`events`](https://docs.developers.optimizely.com/full-stack/docs/create-events){:target="_blank"} and [`attributes`](https://docs.developers.optimizely.com/full-stack/docs/define-attributes){:target="_blank"} in your Optimizely dashboard, and to associate `metrics` with the appropriate Optimizely Experiments. Segment maps Track event names to Optimizely `eventName` - the `eventName` corresponds to an experiment `metric`. In addition, Segment maps Track event `context.traits` to Optimizely `attributes`.

 > If you use Optimizely SDKs v1.x or v2.x and use any `activate` or `isFeatureEnabled` calls, the `attributes` object for each user must match the `attributes` object passed to any Track calls for that user ID so that it can be correctly attributed on the Optimizely results page.
 
 If you are using Optimizely SDKs v3+, [Easy Event Tracking](https://blog.optimizely.com/2019/02/26/introducing-easy-event-tracking-the-easier-way-to-understand-and-optimize-the-customer-journey/){:target="_blank"} is enabled by default for decision events. Set up does not require maintaining the attributes of a user as long as the user ID stays the same between Optimizely `activate` and `isFeatureEnabled` calls and Segment Track calls to have Optimizely `metrics` populated in the Optimizely results page. If you would like to segment your Optimizely results by user `attribute`, then make sure the `attributes` passed in for the `activate` and `isFeatureEnabled` calls match the `attributes` passed in for the Track calls for that user id.
