Perry Marshall has launched two revolutions in sales and marketing. In Pay Per Click advertising, he pioneered many of today’s best practices and wrote the world’s best selling book on internet advertising, The Ultimate Guide to Google AdWords.

More recently, he’s applied the 80/20 Principle to more facets of business than any other author, being the first to expand on 80/20 as an infinite fractal law of nature. 80/20 is the central lever for nearly every profitable strategy in sales, marketing and business. His book 80/20 Sales & Marketing is required reading in many growing companies.

Works also include the bestseller Ultimate Guide to Facebook Advertising (Entrepreneur Press, 2nd Edition 2014) and Industrial Ethernet (ISA, 2nd Edition).

He is referenced in dozens of influential business books by authors like Jay Conrad Levinson, Mark Joyner, Joel Comm, Mari Smith and John Jantsch. He’s shared the stage with Barbara Corcoran, Brian Tracy and Les Brown, having consulted in over 300 industries.

He’s one of the world’s most expensive and sought-after marketing consultants. Direct Marketing maverick Dan Kennedy says, “If you don’t know who Perry Marshall is — unforgivable. Perry’s an honest man in a field rife with charlatans.”

Perry has a degree in electrical engineering and lives in Chicago.
