When it comes to ebooks or info products on ClickBank, I prefer to review them myself before recommending them as an affiliate. That's the only way you'll know if they are worth recommending or not.
Why not start with something easier - things people are searching for online in other niches? In this post I list the 5 things people spend money on: Love, Money, Beauty, Health & Entertainment:

The goal is to choose a niche or a product and create a whole website around it. What you are promoting will determine how you promote it. For example, if I am searching for patio furniture I want to see pictures and prices (not articles). If I am searching for how to treat acne, I want to read how-to information. So you just have to use a little common sense on how to best appeal to your target market and introduce products to them.
Once you pick a general topic, do some searches and make notes of websites you like, what you dont like, and make a list of ideas for your own site.
