You have first of all to search out a market that is hungry for precise data on something. Another way to put that would be discover individuals who are desperate to figure out a problem. Let's have a look at a theme in some detail. Little Tommy comes home from school, he is having a snack and mom notices that he is scratching his head every minute or two. On much closer inspection mom discovers that his hair is full of head lice! She is horrified and wonders how she could have let this happen to her little boy. So she makes a couple of searches related to doing away with head lice. As you are able to see in this scenario the mom is horrified that her little boy has lice and is desperate to discover an instant resolution to do away with them. This is a scenario that is encountered in homes across the globe thousands of times a day. And gives you the perfect chance to dig around for an hour on the net and come up with a resolution to her issue. The following step is to combine the data into a report and put it into PDF format. Come up with a cost of between five and ten dollars then make a simple site or blog to sell it from and drive the traffic to it.
