The personalized content on the homepage is retrieved by executing server-side targeters. The targeters are located alongside the existing Commerce Reference Store targeters in the personalization UI. They are each prefixed with Mobile:

These targeters form three pairs. Each pair is made up of a parent that represents the PromotionalContent items in the top carousel and a child that is made up of a set of products that are related to that PromotionalContent item, displayed in the bottom carousel. An example of such a pair would be MobilePromotionParent1 and MobilePromotionChild1.

The pairs will return different items for the different user segments that are already configured for Commerce Reference Store. For example, an anonymous user might see Promotional Content for free shipping, homeware items, and featured products, while a user belonging to the “Fashionista” segment may see recommendations from Oracle Recommendations, women’s clothing items, or other items.
