Some niches, as you'll discover, aren't as profitable as others. You need to look at your audience and see if they're willing (and able) to spend money for the solutions they're seeking.

As an example, golfers have to have spare cash because the game of golf in itself is expensive. They're also fanatical about the game and would do anything to improve their score or beat their friends on the golf course.

But another niche, such as single moms on a budget may not be willing to pay $67 for an information product showing them how to get organized. Sometimes it depends on the solution itself. Targeting this same niche of single moms, you may find some are willing to pay $47 for an eBook that shows them how to make more money working from home than they do in their regular 9-5 jobs.

One good place to start is with online groups and forums. You can go to iVillage or Yahoo and see what kind of groups garner the most posts. Men's groups such as AskMen might give you insight into what kind of information products this portion of the population might need that help you generate a handsome profit.

What you really need to do is find groups of people with a lot of problems. Then you'll want to have a whole range of products that focus on the same niche, so you can then follow up with "backend sales" to existing customers.

Sometimes, you'll find one large niche and then realize you need to build your information product line around a more targeted, narrow niche of people. For instance, parents in general have many problems you could address, such as raising smart kids, dealing with discipline, and saving money.

But you can then reduce that niche to moms or dad and go deeper by aiming at divorced parents or parents raising kids with illnesses. All you need to remember is that an information product is just a solution, so it needs to be presented as something that will benefit others.
