@futuretrainee Well done.
What's your customer profile? Where can you find more of them? What problem are you solving for them?
Your best bet is to start with a plan. You have to be clear on who you are target customer is.
Now, the secret is, there is no generic answer to your question. Every success story has a unique aspect. But what they all have in common is they went to where their customers are.
Your next nine customers will probably all come from different sources. That's great. Don't worry about scalable tactics right now.
What you need is to streamline your offer. Figure out the sweet spot for what people want from you. Then, you start writing sales copy and content based on what you discover. So you get feedback, apply it to your messaging, and back again.
What you are looking for is how to crack your market. What's that offer that they can't resist. What are they already looking for within what you have.
Once you have discovered that, you can then look for ways to scale your marketing.
But right now, you fortune lives in the manual work you do.
