For a product, I added all the fields, and the product doesn't show anywhere on front end Magento. These are the things I did:
-I added the product in admin
-Added fields:
-General -> Sku, Weight, Status(Enabled), Visibility(Catalog, Search)
-Prices -> Price, Tax Class
-Added images
-Inventory -> quantity is set
-Inventory -> Stock Availability = In Stock
