This podcast offers a step-by-step guide on creating product parentages on Amazon using a Flat File Upload, which is a more dependable option than the Variation Wizard. The speaker, a sales director at My Amazon Guy, walks listeners through the process of downloading a template, entering essential product information like SKUs, product names, and variation themes, and then uploading it to Amazon Seller Central. Key steps include selecting the right product category, deciding whether to "update," "partially update," or "delete," and specifying the parent and child SKUs. The speaker stresses the need for accuracy to prevent errors and notes that the entire process usually takes around 24 hours to complete.
