# Can I make a comparison for each reporting?

### What is a reporting comparison?

A reporting comparison is used to analyze different variations of a feature. It allows our Bayesian algorithms to accurately determine which variation will perform best in terms of earnings, conversion rate and so on.

### Which use case is it available for?

Being able to compare several variations is only applicable for **A/B tests**.\
In **Feature toggling**, there is no variation to compare when doing feature management, as we are evaluating the individual performance of the feature itself.\
For **personalization**, we are mainly looking to create several scenarios for specific audiences, and separately analyze their performances.\
For **progressive rollout,** we are looking to deploy a feature gradually to your users and want to measure the effectiveness of the feature deployment.
