Before you start investing money into paid ads, you need a few basic pillars established first.
You need to have a steady base of recurring customers.
This does not have to be 1,000 returning monthly customers—it can be as little as 5-10.
But this shows your business a few things:
Your product is good
People like your product
You know more about the people who are buying your products
If you have not sold anything or only sold a few products to people that don’t seem to purchase again, I would recommend not investing in paid media just yet.
You also need a steady source of new business.
