About / Contact


Perry Marshall is an author, speaker and consultant in Chicago with expertise in digital communication networks, control systems, acoustics and e-commerce.

His book “Industrial Ethernet” (ISA, 2002 & 2004) was the first trade-published book in its category, and his book “The Ultimate Guide to Google AdWords” (Entrepreneur Press, 4th edition) is the world’s best selling book on internet advertising. His scientific work currently includes power law distributions in consumer behavior, multivariate testing in web analytics, and predictive market research models for online startup companies.

The fields of bioinformatics and the Human Genome Project draw heavily from concepts in information technology. Thus he’s become famous for his landmark presentation “If you can read this, I can prove God exists” which has been downloaded by more than 100,000 people at his website CosmicFingerprints.com. His challenge to atheists, “Show me a message that doesn’t come from a mind,” remains unmet for 10 years and counting.

He observes that both DNA and computer systems employ identical concepts to store, transfer, protect and evolve data – and to the extent science can prove anything, modern communication theory and evolutionary history prove design in biology.
