I have a product in mind of trying to sell online, it is in the health and wellness niche, it relieves pain.
1) How do I use google trends to find out if it is a good product to sell
2) How can i use other platforms like amazon or ebay to find out if the product is a HOT seller or bad seller
3) How do i find out what my competitors are doing is there a tool to find out how much product is being bought from their site
4) What would you do to find out if a physical health and wellness product will sell or not online before you get involved trying to sell it online
