Here is a twist on this Pinterest method: I'm using PPD (pay per download) with recipe ebooks. I use Pinterest recipe boards to drive traffic to my recipe website. Once I have the visitor on my site, and they read through the recipe that got their attention, I place a call-to-action at the end of the recipe. It says "For More Great Recipes Like This Get My Recipe Book - Just Complete An Offer From My Sponsor to Get This Awesome Recipe Book with Over 500 Recipes!" This method is working and I have over 25 recipe ebooks with resell rights that I'm using depending on the types of recipes (meats, desserts, crock pot meals, etc). I make about $1.00 USD every time a visitor unlocks the download gateway to get the recipe book. I'm easily making $25 a day and I've only been doing this since November 2014.
