13-year-old marketing prodigy 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 site. David (who was just 12 years old at the time) wrote a blog article entitled "Drive Traffic To Your Blog - The Advice of a 12-year-old."

This initial article got him on the Digg.com website, which directed a stream of 10,000 visitors to visit his domain in the span of an hour (a phenomenon commonly known online as "the Digg effect"). He has also been featured 4 times on BBC Radio in the United Kingdom. His Internet marketing knowledge and his writing ability is incredible 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 sheds light on some secret AdWords strategies that Google hoped that nobody would ever discover. David has a very solid grasp on Google AdWords Pay-per-Click techniques, which he covers in amazing detail.

He also shows an advanced comprehension of email marketing, with tips to increase opt-in rates and advice on how to turn email list members into buyers. There is priceless information in this section and this can keep the reader from taking incorrect steps regarding 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 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 data that worked in the past but is no longer useful.

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