Hi, I started on eBay, but it was many years ago. Just uploaded products and waited for a customers to come I was not impatient, as selling online was not my priority job that time, I was rather playing with it and frankly I did not believe that time I can make any reasonable money on it. I was patient - focused on something else. I just liked that parcels I send go to many different countries, on different continents. It was somehow fun to me, especially these were goods handmade by my uncle - satisfaction was doubled.
Sells did not soar, they happened from time to time with slowly (!) improving tendency. But someday I figured out, that if I have a product that sells 2-3 times a week with reasonable margin, then having 10-20 of such products would give some extra money and maybe would pay a few bills.
So my begginings were not impresive, but I was not under any pressure. If I would start today with a new product group, I would: - open accounts on most important marketplaces (depeneding on what you sell) - prepare perfect photos - prepare good content - upload your wares there were accounts were established - ...wait and see what happens. Waiting time can be spent creatively by preparing your own webstore
