"This is the single best publication about search engines that I have read, and I believe, that exists! Anyone whose business is affected by the behavior of search engines MUST READ this report. Even if they don't understand it all -- you included every tidbit of juicy information that most other publications gloss over, but I LOVE -- they will understand SO MUCH MORE after reading your report.

I've been writing about search engines and optimizing my own sites for search engines since 1997, when I wrote The HTML 4 Bible, and in all my research and interviews, I've never been able to find so much valuable information -- all in one place. This is book is a graduate education in search engine optimization.

Perhaps the most important thing you've done is to remove much of the mystery from an industry that is known as the dark side of online marketing. I've always contended that the "mysterious ways of search engines" is marketing blather from optimizers who either don't know how things work, or want to keep clients in the dark -- after all, search engines are computer programs, and computer programs just follow the rules written by human beings.

If there is ever a certification program for search engine optimization professionals (SEOs), this book will be the textbook, and the certification exam will be based on knowing this level of detail. Congratulations on far, far exceeding my considerable expectations!

Congratulations, sincerely. With this, I believe you may have become the most influential writer in the SEO industry."
