Exceptions & Fallback

Even with well-defined rules, there are always cases where the expected product set cannot be fully generated. To ensure stability and consistency of your strategies, exceptions and fallbacks are built into the rule engine.

Exceptions

• Allow you to exclude specific cases or define special treatments.

• Example: If the current product belongs to “outlet” category, exclude it from recommendations.

• Practical use: avoid showing restricted categories, duplicate products, or unwanted items in a given context.

Fallbacks

• Define what happens if a rule does not return enough products (e.g., fewer than the required 12).

• Examples:

  • Fill remaining slots with global top sellers.

  • Show a default curated list.

  • Hide the block entirely (last-resort option).

• This ensures no empty space in your templates and guarantees a predictable user experience.

Exceptions & fallback rules provide resilience. They prevent broken layouts, ensure continuity of engagement, and avoid showing irrelevant or empty recommendations
