Aarron Walter has written a very clear book on all the essentials of what he calls "findability" for modern-day websites. Too bad I found this book only after spending way too much time reading various websites about many of the different subjects he deals with in this book. This book is a shortcut for a long learning curve and I wish I had known about it before. But still, I learned a few new tricks and have put them into practice immediately.
Aarron is clearly an author who's "into the business" himself, and not someone who studied the subject just for the purpose of writing a book about it.
Well recommended for anyone who's into building websites, whether you're a coder, designer, information architect or the 'all-in-one' type like myself.
