I looked through most of the coding examples in this book and nearly all of them are pretty much useless if you are doing anything serious with adsense and adwords. However he does have a good understanding of how the adsense and adwords programs work so I was able to pick up information about that.

Don't bother reading this if you are looking for any kind of technical information, some of the code is bad, and most of it doesn't really do anything that effective. It is a good pickup though if you are looking for understanding on Google, although much of this information is available on the web. I get the feeling he has more of a marketing/business background as opposed to computers.
