A/B Testing: Targeting

Show tests only to specific audiences so results stay clean and relevant.

Who sees the test with audience targeting open
Who sees the test → Choose visitors: device type, visitor type, country, UTM parameters and the sample rate.

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 Who sees the test → Choose visitors, the Sample rate runs 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. Visitors who are in the test are always split evenly between the original and your variants.

Tip

Keep targeting simple. The more you slice traffic, the longer it takes to reach meaningful sample sizes.
