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
In order to protect our partners’ data, we do not allow lookalike modeling off of 2nd-party data.
- Sufficient 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.
If you have any questions or believe there may be an issue with lookalike reporting, please reach out to the Salesforce DMP support team.
