13-year-old net genius David Wilkinson has just released his first ebook, available for immediate download.

David, also known as "the affiliate kid", received his first big break as a guest blogger on Problogger, which is a highly trafficked blog. David (who was just 12 at the time) posted a blog article with the title "Drive Traffic To Your Blog - The Advice of a 12-year-old."

This initial article landed him on the Digg.com site, which led a stream of 10,000 visitors to visit his blog in the span of an hour (a phenomenon commonly known to web marketers as "the Digg effect"). He has also been a guest 4 times on BBC Radio in the United Kingdom. His Internet marketing knowledge and his writing ability is amazing for any age, and even moreso for a 13-year-old.

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

It exposes some hidden AdWords strategies that Google hoped that no one would ever uncover. David has a very solid grasp on Google AdWords Pay-per-Click methods, which he covers in great detail.

He also shows an advanced understanding of email marketing, with tips to improve opt-in rates and suggesions on how to make subscribers into buyers. There is priceless information in this section and this can help the reader avoid taking the wrong steps regarding their email marketing methods.

Bottom line, an email list is useless if there isn't a way to turn subscribers into buyers. David has some advanced ideas and techniques to help convert lists into money centers.

Affiliate Defined also encompasses viral marketing, including how to properly go about it. David has spent the last year compiling information and revising it so that it offers genuine value to his readers. It features all-new content that is known to work in 2008, not rehashed info that worked in the past but is no longer useful.

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.
