Creating segments you can't act on. Keep segments actionable and manageable.

2. Static Segments

Not updating as customers change. Regular refresh and dynamic rules.

3. Data Quality Issues

Basing segments on bad data. Clean and validate data first.

4. Ignoring Small Segments

Missing valuable niche groups. Balance size and value.

5. No Activation Plan

Creating segments without using them. Plan activation before segmentation.
