Personalization re-ranking levels

Personalization Re-Ranking controls the impact of personalization on boosting records. Explore the range of personalization levels to find the best match for your search, from lower to higher:
  • None. Disables personalization, ensuring all users see the same arrangement of search results.
  • Low. Implements minimal personalization by subtly reordering search results to start aligning with individual user preferences.
  • Medium. Enhances personalization by adjusting the ranking of search results more noticeably, for a tailored user experience.
  • High. Amplifies personalization significantly, deeply customizing the order of search results to match user preferences closely.
  • Maximum. Delivers the ultimate level of personalization, radically transforming the order of search results for optimal relevance to each user.
If Personalization Re-Ranking is set to maximum, Algolia prioritizes Personalization over business relevance since records boosted by personalization can reach the top position in the textual bucket. You can run A/B tests to compare the performance of different levels of personalization re-ranking. This empirical approach lets you observe the impact on real user interactions, helping you make an informed decision that aligns with your business objectives and user preferences.

Enable Advanced Personalization with Personalization re-ranking

Advanced Personalization uses both Personalization Re-Ranking and enablePersonalization to determine how personalization affects your search results.
  • If the personalization re-ranking level is set to None and enablePersonalization is false, Advanced Personalization won’t apply because personalization is off for the index.
  • If the personalization re-ranking level is set to anything other than None and enablePersonalization is false, Advanced Personalization won’t apply. Personalization must be enabled for it to take effect.
  • If the personalization re-ranking level is set to None and enablePersonalization is true, Advanced Personalization won’t apply until you choose a different re-ranking level.
  • If the personalization re-ranking level is set to anything other than None and enablePersonalization is true, Advanced Personalization will apply based on the chosen re-ranking level.
