## Benefits

Advanced Personalization offers several advantages:

* **It's easier to set up.** Advanced Personalization automates and, hence, speeds up the deployment of a personalization strategy.
* **It generates unbiased user profiles.** Classic Personalization can lead to biased or inconsistent user profiles. By automating the process, Advanced Personalization helps eliminate these biases.
* **It predicts user preferences.** Advanced Personalization can predict [what users might like or dislike](/doc/guides/personalization/advanced-personalization/what-is-advanced-personalization/in-depth/how-does-advanced-personalization-work#user-profiles). This means it can better customize the experience for each user based on their unique tastes.
* **It generates more accurate user profiles.** Advanced Personalization generates user profiles based on [signals from your users](/doc/guides/personalization/advanced-personalization/what-is-advanced-personalization/in-depth/how-does-advanced-personalization-work#translate-user-behavior-into-affinities-through-events). The stronger the signals, the more accurate it can be in understanding each user.
* **It enhances monitoring and testing.** You can use the [Algolia dashboard](https://dashboard.algolia.com/advanced-personalization/overview) to inspect your user profiles, simulate search personalization experiences, or [conduct A/B tests](/doc/guides/personalization/advanced-personalization/monitor/in-depth/ab-test).

## Considerations

Before choosing to migrate from [Classic Personalization](/doc/guides/personalization/classic-personalization/what-is-personalization) to Advanced Personalization, you need to consider the following:

* **Advanced Personalization deactivates Classic Personalization.** You won't be able to update your Classic Personalization setup.
  This includes, your strategy, [`facets`](/doc/api-reference/api-parameters/facets),
  and [`personalizationImpact`](/doc/api-reference/api-parameters/personalizationImpact).

* **Your events and <Index /> data won't be changed by the migration.**

* **User profiles stop personalizing search results**.
  Classic Personalization will stop personalizing search results for already generated user profiles until your Advanced Personalization setup is complete.

* **Migration can be rolled back during beta.**
  To revert to Classic Personalization,
  contact the [Algolia support](https://support.algolia.com/hc/en-us/requests/new) team.
  By rolling back the migration, you lose all changes made in Advanced Personalization.
