The best list to have is of paying customers. This will make sure you have only customers on your main list.
- Find popular keywords people are looking for to solve a problem – either in your area of interest or an area you would like to enter.
- Research the subject thoroughly.
- Write a one page paper on the subject giving all the main points – anyone who reads this should save hours or days of work and still get all the good stuff.
- Sell to the same audience using these keywords online – for a low price.
Some of these steps (or all of them) can be outsourced.
The first one is the key – you have to start with what they are looking for (a solution for a problem) and give them an irresistible deal: the easy, short and very cheap way to know all they need about their problem. This is not necessarily the actual solution to their problem, but it’s the map to find the right one for them.
