How handy that there are so few basic structures for effective advertisements! Learning these can help you produce more creative content and more effective marketing materials. I have attached the original article, so you can see the evidence for yourself, as well as a blog post that summarizes them for you and provides some new examples. I apologize in advance if you start to categorize all the ads you encounter according to their template.
P.S. A timely article in the New York Times re-emphasizes that creativity can be taught.
