I would like to have information about Data Feed Manager. Is it possible to send it is produced on ebay or google shopping ? How this this past? ebay should create an account to import the products ? I have configurable product how will it be showing on google shopping?
By default, magento does not contain the ability to generate the data feeds for Google Shopping or eBay.
To generate magento google shopping data feed, you can use ready-made extension that already contains data feed templates and you only need configure filtering of products for uploading.
