- A/B test. Create a modification with two or more variations to test which variation performs the best. You manually define the variation distribution, that is, the percentage of eligible visitors to whom each variation is shown.
- Multi-armed bandit. Create a modification with two or more variations, and select a multi-armed bandit algorithm for automatically optimizing the variation distribution over time. The better a variation performs relative to the other variations, the bigger the portion of visitors to whom the platform shows the variation.
- Personalization. Create a modification with a single variation to provide personalized content to your visitors.
- Selective profiling. Create a modification with a single variation (and no comparison group) to provide non-personalized content that is safe to display to visitors who have refused profiling. This case is only available on sites that have the selective profiling module enabled. For more information, see Visitor profiling solutions.
