Hi, We are an e commerce company that has our own domain but also sell the same products on eBay and Amazon. What is the feeling on the same exact descriptions being used on different platforms? Do they count as duplicate content? Will our domain be punished/penalised as our domain does not have as much authority as EBay or Amazon? We have over 5,000 products with our own hand written product descriptions. We want our website to be the main place/ have priority over the above market places. What's the best suggestion/solution? thanks,
