I got started in affiliate marketing in May of 2004, and it was all due to an ebook I bought called GoogleCash. The book had just recently come out and it was a great resource and introduction to Pay-Per-Click (PPC) marketing using Google Adwords. Since that first edition the book has been updated a couple of times, and is now on its third edition; as Google has changed their own tactics over time the ebook has evolved as well. This book is probably one of the best introductory resources to PPC you will find on the internet. It is the one that got me started and I can truthfully say the techniques I learned from it have earned me thousands of dollars.
GoogleCash is written for beginners and starts at square one, making it a perfect introduction, answering all the questions that someone who has never done this before would have. It walks you through the steps in finding an affiliate product to market, then how to create advertising for that product using Google Adwords, and then some good methods for creating well-performing ads and maintaining a successful ad campaign. Along the way the reader gets a complete introduction to the world of pay-per-click.
Simply put, GoogleCash3 is Pay-Per-Click Advertising 101 for any aspiring internet marketer.
