Common Reasons for why a segment may not be available for lookalike modeling:
- The lookalike report for this segment has not yet been calculated
Lookalike reports are processed every weekend. If this segment is too new to have gone through its first processing cycle, then please check back next week.
- The segment is too small
Segments must meet a certain threshold for lookalike reports to be calculated. This threshold is the greater of 5,000 devices or 0.02% of the overall audience of the client.
- The segment contains 2nd-party Data
2nd Party Data is blocked by default from being using in modeling. Data Owners who share their data must opt in explicitly for data to be available to be used in lookalike models.
- The segment contains real-time seed segments
Real-time segments cannot be utilized for lookalike modeling.
- Insufficient segment data in DMP instance to construct the lookalike models
The instance must include at least 10 segments before lookalikes can be generated. The 10 segments must be either 1st- or 3rd-party segments, with the exception of 3rd-party extension segments.
- Existing lookalike segments are included in the rule set
Lookalike segments cannot be further modeled; if an existing lookalike segment is used within a rule group, subsequent lookalike modeling is not available.
- Certain 3rd party data providers
Some 3rd party data providers do not allow their data to be used for lookalikes. If your segment contains data of one of these providers, the segment is not eligible for lookalikes.
