Query: A must-have for a web developer's bookshelf

I'm a web designer branching out into search engine optimization and marketing so that I can provide my clients the full package. This is just the book I need. The material is current, proven reliable, and covers everything I need to know to create a winning site, from design to dollars. I can't recommend it enough. Many thanks to the authors.
