Hi dj,
So far I've got my ideas by asking friends and family about things they are knowledgable or want to sell online. I then go to word tracker to find the niche if there's one. Suddenly within 2 weeks I've got more ideas then I can handle.
Ask yourself: What are your interesting. What would keep you interested in a project?
Have you ever searched the web for something you really wanted and couldn't find?
Have you looked through the click bank products to give yourself some inspiration. I started making a list when looking through clickbank of only the items I liked and wanted to sell.
Start making a list of these things over the next few days and then check out wordtracker to find the niche and the keywords to use.
And come back with any questions
