The main thing you need to do is make sure you sell products that there is a market for and that have enough profit margin to be able to pay for ads and make a decent profit.

Stay away from low price products. Profits will be too low.

If you want to make $5,000 a month, it’s easier selling 100 products that have $50 profit than it is selling 1,000 products that have $5 profit. In the latter case, you’ll have 10 times more customer support, packing, shipping, etc.

Product selection is the most difficult. I would suggest finding suppliers in a smaller niche where there’s less competition.

Sell products that people are searching for on Google. It will then be easy to run Google ads and get sales.

Make sure your website looks professional and include a phone number that customers can call you on.
