compose audience vs segment builder

@wuwei88  points to consider here 

• Audience Composition 
  •  more suited for curating and personalizing audiences based on existing segments.
  • useful for larger audience combining smaller ones 
  • provides options to , split, ranking and overlap audience based on the  specific criteria
  • Has limitation on the number of audience 
• Segment Builder
  •  ideal for creating new audiences from scratch using detailed profile data.
  • perfect for audiences based on specific attributes or behaviors or marketing needs for given use case
  • Provide granule support for segmentation based on the profile and event schema 
  • Not ideal for complex audience 

Hi @wuwei88 ,

You'd use Segment Builder when:

1. You need granular control over the logic
2. You're starting with raw event or profile data
3. You want real-time evaluation using streaming datasets
   
   

Use Cases:

1. Behavioral Segments

   • Example: Users who viewed a product but didn’t purchase in the last 7 days

   • Built using event datasets like productView, purchase, etc.

2. Demographic & Profile-Based Segments

   • Example: Customers aged 30–40 in New York with Platinum loyalty status

3. Real-Time Personalization

   • Example: Visitors who added items to cart in the last 30 minutes

   • Uses streaming data with real-time evaluation

4. Time-Based or Frequency-Based Logic

   • Example: Users who visited the site 3+ times in the last 14 days

5. First-Time or Lapsed Customers

   • Example: Profiles with no purchases in last 90 days, but had one before

You'd use Compose Audience when:

1. You want to combine existing segments without redefining them
2. You value simplicity and reuse over raw-data complexity
3. You’re building target groups for a campaign or activation

Use Cases:

1. Audience Reusability & Modularity

   • Example: Combine "Frequent Visitors" AND "High-Value Customers"

   • Encourages clean, modular segmentation logic

2. Exclusion Logic

   • Example: Send campaign to "Engaged Visitors" but NOT "Recent Buyers"

3. Campaign-Specific Audiences

   • Example: Campaign targeting = (Cart Abandoners OR Wishlist Adders) AND NOT (Past 7-day purchasers)

4. Region or Channel Specific Roll-Ups

   • Example: "All European Audiences" = France OR Germany OR UK segments

5. Simplify Complex Campaign Logic

   • Compose audience as an "umbrella" over existing tested segments
