Eliminate empty or partially filled recommendation blocks by selecting a relevant fallback recommender to fill open slots. When a primary recommender with restrictive filters returns insufficient items, the fallback recommender automatically provides additional suggestions to complete the set. This safety net protects the integrity of your campaigns and ensures that your users always get a full list of recommendations. At the same time, Salesforce Personalization avoids duplicate recommendations and ensures that each item is suggested only once per set of results.
