From Spiffy Stores Knowledge Base
Setting up a product data feed for your products is a great way to get added exposure for your online store by syndicating them to a variety of these shopping portals.
Product data feeds are updated whenever you make a change to your products, so you can be sure that they're up to date. To create a data feed for Shopping.com follow the instructions below.
Step 1 - Create a collection of products
Firstly we need to have a list of products to send to Shopping.com. To create this, you'll need to create a collection that contains all of the products you want in your data feed. You can create a Standard Collection or a Super Collection. This can be done in the "Collections" section of your store's Toolbox.
If you already have created a collection for another provider (for example Google Merchant Center) then you can skip this step.
Step 2
1. After you have created your collection, go to the "Marketing -> Product data feeds" section of your store's Toolbox, and click the "Activate" button in the Shopping.com section.
2. Enter a name for your feed. It's npot used anywhere except for your reference.
3. Select the collection you created in Step 1
4. Click the "Activate button"
