# Defining Audience Segments for Audience Personalization

If everyone sees the same page, you end up guessing what works. Audience segments fix that.

In this guide, you’ll learn how to define the right visitors for each variant so your personalization is targeted, measurable, and easy to scale.

**Before you begin:** Make sure you are already inside the Audience Personalization campaign setup flow and you can see the Audience segmentation section.

**Why this matters:** Audience rules decide who sees which experience. Clean segments mean cleaner learnings, and faster wins.

### What you can build segments with

Audience Personalization lets you define segments using these rule types:

* **Location:** Segment visitors by geography.
* **UTM parameters:** Use utm\_source, utm\_medium, utm\_campaign to target visitors based on how they arrived.
* **User type:** Separate new visitors and returning visitors.
* **Device:** Target desktop, mobile, or tablet visitors.
* **Browser:** Target visitors using a specific browser.
* **Operating system:** Target visitors using a specific OS.
* **Referral URL:** Target visitors based on the URL they came from.

**Pro Tip:** Start simple. One strong segment beats five messy ones.

### Step-by-step: Define your audience

Use this when you want to create segments one by one.

#### Step 1: Add your first segment

Click **Add First Segment** to get started.\
You’re setting the foundation for who should see your first personalized experience.

#### Step 2: Choose a rule and set conditions

Select a rule from the list, then define the condition.\
Example: UTM parameter utm\_campaign contains “brand-search”.

#### Step 3: Combine rules to refine the segment

Add more rules to narrow the audience.\
Example: target new visitors from Australia.

Nice. Now you’re targeting intent plus context, not just traffic.

#### Step 4: Create additional segments

Repeat the same approach to create more segments.\
Each segment can map to a different personalized variant later.

  Then click **Create Segments**.

#### Step 3: Fill in conditions for each segment

Define the rule conditions for each row.\
Once the conditions look right, you’re ready to use them in your campaign flow.

{% hint style="info" %}
In case you have missed any rules or need more/less segments, you can "Add Row", "Remove Row" and "Add/Remove Rules".
{% endhint %}

#### Editing in Bulk Mode

If you need to change the setup mid-way, you can:

* **Add Row**: add another segment
* **Delete Row**: remove selected segments
* **Add Rule**: add a new rule to define the segment
* **Remove Rule**: remove an existing rule from the segment
