Common Targeting Dimensions
- Device: desktop vs mobile behavior often differs
- Visitor type: new vs returning visitors
- Campaigns: target traffic from specific UTM sources/mediums/campaigns
- Country/region: when messaging differs by locale
Traffic sampling
Under Advanced you can run a test on only a share of eligible visitors (for example, 50%). Sampling and targeting are enforced by Zolvio’s servers, so a visitor who isn’t in the sample simply sees the original—no variant is applied or recorded for them.
Tip
Keep targeting simple. The more you slice traffic, the longer it takes to reach meaningful sample sizes.
