What would a marketer include in a Recipe if they want the visitor's affinity score to be taken into account when showing recommendations?

A "Booster" is a rule within an Einstein Recipe that modifies the ranking of recommended items based on specific attributes. To incorporate a visitor's affinity, a marketer would configure a booster to promote items that match the visitor's calculated affinities (e.g., for a specific brand, category, or style). This allows the recipe to prioritize items that are more relevant to the individual's tastes, refining the output of the base algorithm (ingredient).

A. Exclusion: This completely removes items from the recommendation pool based on a rule; it does not re-rank them based on affinity.

B. Ingredient: This is the core algorithm that generates the initial list of recommendations before any ranking adjustments are made.

C. Variation: This is a concept related to A/B testing different campaign experiences or recipes, not a component within a single recipe's logic.
