The stage will include auto Images upload on server and Amazon, Auto content generation related to product through configuration within the proposed tool and keyword management based on preset configuration. We are targeting for end to end automation with a simple and highly configurable tool . Technology is not a constrain (if excel works even excel will do). To sum it up, the automation should be able to pick up images and upload, generate fields needs for listing , generate keywords based on preconfigured setting, create list file without error, Upload listing and maintain the records. This should be ongoing process and refresh the product listing on periodic basis with new keywords. Sample Product listing file attached.
