Product Ads sellers that also use Google Base can now upload their Google Base product .txt file to Product Ads via Seller Central in just a few steps.
There are two ways to do this:
1. The simplest method is to upload your existing Google Base feed without modifying your current Google Base feed. To upload your Google Base feed go to the PRODUCTS tab in Seller Central and select Upload Product Ads from the top navigation. Use the drop down menu in Step 1 to select ”Upload Google Base Feed”.
2. You can also upload an enhanced attributes Google Base feed (.txt). This is a good way to improve categorization and display richer product pages to Amazon.com customers. If you do not have Category data in your Google Base feed or wish to exclude products from listing on Product Ads, consider adding these attributes to your file. You can also create custom fields in your feed to include information like Brand, Department, UPC, Image, Description, Manufacturer, and Manufacturer part number.
