Returning Items Similar to Cart Items
Customers demonstrate their interest in an item by putting it in their shopping cart. Showing customers
similar items to what they already have in their cart is a good way to spur add-on sales.
The CartSimilarities response group, which works with most cart operations, returns items that are similar
to the ones included in the cart request. Items are returned based on:
• Similarity—Items are similar to the one purchased
• Items viewed—Customers who viewed the item in the cart also viewed the items returned by this
response group
• Similar items—Similar items in other product categories
Each of these similarity types have their own element tag: <SimilarProduct>, <SimilarViewedProduct>,
and <OtherCategoriesSimilarProduct>, respectively, as shown.
