You'll have to be more specific.
There are many ways to attract, connect, and engage with your target audience.
When you say "that nobody is actively looking or searching for?" , do you mean that nobody has ever thought about buying what it is that you want to sell and you don't even know who would be interested to buy it?
Or are you assuming that their is a group of people that you know would be eager to buy if only they understood the benefits and you want to reach out and touch them?
