Thirteen-year-old web wiz-kid David Wilkinson has just released his first ebook, available for immediate download at http://Affiliateredefined.com

David, also known as "the affiliate kid", got his first big break as a guest blogger on Problogger, which is a very popular blog. David (who was just 12 years old at the time) wrote a blog post with the title "Drive Traffic To Your Blog - The Advice of a 12-year-old."

This initial post got him on the Digg.com website, which led a stream of 10,000 visitors to visit his website in the span of an hour (a phenomenon commonly known online as "the Digg effect"). He has also been featured four times on BBC Radio in the United Kingdom. His net marketing knowledge and his writing ability is astonishing for any age, and especially for a 13-year-old.

So what does his ebook contain? "Affiliate Defined" is a 221-page ebook, which is nearly thrice the size of the average ebook on the market today.

It sheds light on some back-door AdWords methods that Google hoped that no one would ever discover. David has a very solid grasp on Google AdWords Pay-per-Click techniques, which he covers in amazing detail.

He also exhibits an advanced comprehension of email marketing, including tips to increase opt-in rates and advice on how to make subscribers into buyers. There is priceless information in this section and this can help the reader avoid taking incorrect steps in regards to their email marketing methods.

Bottom line, an email list is useless if there is no way to turn subscribers into buyers. David has some advanced methods and strategies to help turn email lists into "cash-producing machines."

Affiliate Defined also encompasses viral marketing, including how to properly set it up. David has spent most of 2007 compiling information and tweaking it so that it provides actual benefit to his readers. It features all-new content that is known to work in 2008, not old info that worked in the past but is no longer effective.

At 221 pages, there is far too much to cover in this article, so do yourself a favor and head over to David Wilkinson's site and review it for yourself.
