Well, it might be because of one of these 3 reasons.
1. People don’t know you exist.
It’s either because you don’t do enough marketing or your marketing isn’t working. The world is a noisy place. You have to do something to get people’s attention.
2. They aren’t ready yet.
They know you. They are interested. But they aren’t ready to commit yet. You can’t convince people to buy, that’s their decision to make. What you can do is help them decide.
3. You’re not for them.
Remember that you are not for everyone and that’s okay. You don’t have to be. Find people who need your product in their life. You don’t sell a shampoo to a bald guy.
