[​](https://app.netspring.io/documentation/docs/Build%20Visualizations%20and%20Dashboards/segmentation#overview)The Segmentation section in Optimizely Analytics templates lets you segment reports by cohorts or attributes. You can use pre-saved definitions of cohorts or attributes for segmentation or define them inline as part of the report.

### Segmentation using cohorts

The **Segment by Cohort** section lets you segment your results using cohorts. A **Cohort** is a subset of the dataset you chose for your exploration. It enables more advanced definitions, combining multiple property filters with behavioral filters.

For instance, you have a **Users** dataset with a record for each user and a **Page Views** dataset that logs each page view event per user. With this feature, you can define a cohort in the **Users** dataset to include only those users with 10 or more **Page Views** in the past week.

So, when you select a cohort in this section, you tell Analytics which category of users your segment draws from.

To add a cohort as a segment,

1. Create or open any exploration template, go to the **Segment by Cohort** section, and click **+**.
2. Choose a cohort from the drop-down list or add a new cohort inline by clicking **New Cohort**.
3. Run the exploration and click **Save**.

### Segmentation using attributes

To segment your analysis further, you can group events by individual attributes. An attribute is a column within a dataset that reflects a qualitative or categorical trait of the entity it represents.

When you add a property, Analytics applies it to all the events in your analysis and then groups your results by the property you choose – such as user country, subscription tier, or account status.

For example, if you select the **subscription\_tier** property in the **Subscriptions** dataset and have four subscription tiers (**Free, Standard, Premium**, and **Ads Plus**), you see one line in the chart for each.[​](https://app.netspring.io/documentation/docs/Build%20Visualizations%20and%20Dashboards/segmentation#segmentation-using-attributes)

To add an attribute as a segment,

1. Create or open any exploration template, go to the **Group by Property** section, and click **+**.
2. Choose an attribute from the drop-down list and click **Save**.

**Note**

When you perform segmentation, the section only displays join path-compatible suggestions in the drop-down list. Analytics displays the incompatible options in grey with a warning symbol.
