Before you begin
Make sure to also integrate the [Relevance by Segment API](🔗).
You can learn more about Relevance by Segment on the [feature page](🔗).
Add pixel parameters containing segment name and values to capture analytics for those segments. Segment information must be added to both [page view pixels](🔗) and [event pixels](🔗). Currently, the following segments are supported:
| Column Title | Column Title | Column Title |
| **Segment name** | **Description** | **Sample values** |
| customer_tier | Tier that the user belongs to. | Premium<br><br>Gold<br><br>Base |
| customer_country | Country that the user belongs to or is accessing the site from. | US<br><br>Australia |
| customer_geo | Geography or Region that the user belongs to. | Florida<br><br>Asia |
| customer_profile | Profile of the user. | Healthcare<br><br>Cleaning |
**Using an existing pixel parameter as a segment** In addition to the above segments, you may also use any existing pixel parameter, such as view\_id, user\_id, etc., as a segment. If you choose an existing pixel parameter as a segment, then additional pixel integration is not required.
### **Defining Segments**
Add your segment parameter in the following format:
Where \<segment_name> is the name of the segment, and <value> is a string containing the segment value.
The value string may only contain alphanumeric characters (a-z, A-Z, 0-9), hyphens (“-”), or underscores (“\_”). It is case sensitive.
A segment can have up to 5000 unique values, though we don’t recommend using a segment with so many values since it can thin out the data used for ranking. If you do have a use case for using more than 5000 unique value, please consult a member of the Bloomreach team.
**Example Segment**
For a segment named customer_tier with a value of premium, the pixel parameter is:
