A client wants to display the most-purchased products in a specific category on that category's landing page. Which Target request (mbox) parameter should be populated on that page?

Question

Options

• Aentity.categoryId with one or more values separated by a comma
• Bentity.id with one or more values separated by a comma
• Centity.id with a single value only
• Dentity.categoryId with a single value only

• A
  7% (3)
• B
  10% (4)
• C
  2% (1)
• D
  80% (33)

Explanation

Option D is correct because a category landing page represents a single, specific category context - passing entity.categoryId with one value tells Adobe Target which category the visitor is currently browsing, enabling Recommendations to surface the most-purchased products within that exact category.

Why the distractors are wrong:

• A is wrong because entity.categoryId with multiple comma-separated values is used on product detail pages to indicate all the categories a single product belongs to - not on a category landing page, which has one defined category context.
• B and C are wrong because entity.id identifies a specific product (SKU/item ID), not a category. Using it on a category page would tell Target you're viewing a product, not a category section.

Memory tip: Think of it as "one page, one category, one value." A category landing page has a single identity - the category itself - so entity.categoryId gets exactly one value. Save the comma-separated lists for product pages that need to declare membership in multiple categories.
