Very shortly I will be creating highly targeted niche Content Websites designed to make money with Adsense and affiliate products.
Before you can start building sites you need to do a lot of research and I came across a great site that can help you get some great ideas on what to create a site about.

For example if you are thinking of doing a content site or sites on a subject such as horse riding, simply type in horse riding into http://www.kwbrowse.com and watch what happens. All of a sudden it comes up with numerous related topics to horse riding, not just hundreds of keywords with horse riding in it as for example the Overture Suggestion tool would do.

This is a very powerful and time saving tool that should be in your favourites!
