Groups viewable recommended products by product category.
This dimension is created automatically when the product status viewable-reco is sent for a product in this category. Recommendation Tracking documents when a product counts as viewable.
Note
This dimension is only filled when the Recommendation Tracking extension is implemented.
Example
A recommendation widget below the fold loads with four products: Product A (40), Product B (30), Product C (20) and Product D (10). The visitor scrolls down. Products A and B become completely visible, Product C is only ever partly on screen, and Product D is never reached. The visitor then clicks Product A and buys it. Products A and B belong to the category Shirts, Products C and D to the category Shoes.
The dimension lists Shirts only. Shoes is missing because neither Product C nor Product D was ever completely visible.
