Scientific Advertising by Claude C. Hopkins

Without a doubt, this is one of the most widely read and influential marketing books of all time. Nowhere else can you get such a clear and concise education on the most essential principles that make up the foundation of modern marketing.

You’ll discover how to appeal to consumer psychology, how to craft more compelling sales copy, how to write better headlines, and much more.
