You can now assign your campaigns to exclusion groups — ensuring that visitors are only exposed to one experiment or personalization within a defined group at a time.

This prevents test collisions, conflicting experiences, and diluted results. Perfect for running:

• Multiple homepage tests without interference

• Theme vs. offer tests with clean traffic splits

• Sequential rollouts where overlap could bias outcomes

Create a new Exclusion Group from your campaign settings and assign experiments with a click. Personizely will automatically ensure that visitors are bucketed into only one campaign within that group.
