I just noticed that "Entreprenerd: Marketing <for> Programmers" is free as well on your website. Nice!

> A modern web-marketing book that outlines a multi-modal system for growing a website with SEO, Google AdWords/Facebook Ads, Conversion Optimisation, Copywriting/Classic Persuasion/Behavioural Psychology, Google Analytics, Statistical Significance, Email Marketing, and Remarketing. When I launched my first web application it started off with zero traffic. This obviously was not satisfactory so I started a private Berlin-based marketing group with local marketing consultants and tech company owners. During these sessions, I was privy to tactics from marketers working with companies like Goldman Sachs, Amazon Audible, Delivery Hero, ResearchGate, etc. To balance things out, I also conferred with people active in the darker side of internet marketing, like guys running shady coupon sites or selling fitness ebooks. This book is the product of what I learned from these sessions and my own experiments.
