This plugin is for e-commerce store owners on multiple platforms looking to make more revenue by expanding. It generates a product feed to be used with all of your e-commerce stores so you only have to update information once, which is a huge time saver. You can install the plugin to the site where your items are and use the product feed to add it to any other marketplace you use (Google Shopping, eBay, etc). If you were to change everything manually, without the product feed, you would have to add it in each place.
Another plugin on their site is Social Booster, which re-shares your WordPress posts to other social medias.
