This filter is product-specific and therefore only works on a product detail page. On other pages, this filter will not provide any results.
This filter retrieves all products that are frequently viewed in combination with the currently viewed product.
Example: Many shop visitors first look at a smartphone and then visit a case via the navigation. If visitors are now on the product page of the smartphone, this filter will suggest a case to them, because these products are often viewed after each other.
