I love learning by reading. However few books in the online and affiliate marketing space have been of the ‘can’t put down’ category. These are the exceptions:
80/20 Sales & Marketing by Perry Marshall.
This book knocks 80/20 out of the park. Perry is a #1 Adwords guru and one day his brain exploded. This book is the result. Read it!
Launch! by Jeff Walker
Jeff Walker is the guy to read/understand/follow for launching products. Launch! condenses his knowledge in a valuable readable and exciting way.
