This book was written in 2007 and so many of its recommends are simply out of date. For example it recommends using Overture which no longer exists.
It does go through the basics and it is very concise, but I cannot say that I have noticed my rankings going up. A lot of it is reiterative and sometimes seems to be explaining the obvious. i.e. things that I had discovered for free by searching the net.
There must be better books on the subject of SEO; however they are probably more expensive than this.
