In order to get your products listed in Google Shopping and upload your product data in Google Merchant Center, you will first need to create a feed to which you can submit your data. This step is required and once a new feed is registered, you can update the existing feed without having to register it again.

Your product data must meet the Google product data specification and policies. In your Google Merchant Center, use the primary feeds to add or remove product data, set language and country targeting, and set Feed Rules for your product data. 

CHECKPOINTS:

A) Ensure you have correctly added your website address and Publish URL in your shop in ShopFactory.

In ShopFactory, product identifiers can be setup in the Product Properties dialog.

- Open your shop in ShopFactory

- You can either go to LIST OF CONTENTS or select the page on the left tree menu -> switch to LIST mode -> select a product then click "Edit Product"
