I am currently taking a course on internet marketing and it is some real interesting stuff! You can really make some money in this. I have been dabbling for a while now, so I am hoping to get serious and build about 10-20 new websites that are solely built as marketing sites monetized with Adsense.
My first of these is a site that promotes Blueair air purifier systems. Blueair is a company that builds air purifiers. What I will do for them is grab people who search for air purifiers and send these people to marketers who actually sell the Blueair systems. Pretty simple, and very complex.. If you are interested in how to do this yourself, just jump in. There is plenty of room to make some money. I can point you to the place I get my information. Just ask!
