I came across this SEO book by Aaron Wall and thought it looked pretty good. It’s packed with information that is not waffle and general, but very specific on do this, do that type of basis.

324 pages of information to be precise on Search Engine Optimization. I recommend you buy it, especially if you are just starting out making your web site or have been in the web site industry for a while but are still puzzled on how to market your web site properly.
