One of the most noticeable and least expensive improvements you can make to increase the speed of your website is to implement these front-end techniques.

It is true that, the 14 principles can be found in the description of the book, or with the excellent YSlow tool delivered by Yahoo! Developer Network.

So why should you buy the book??

The book explains "why" these 14 principles are best, and it does so in a concise format.

If you currently work professionally with the front-end side of a website (or would like to someday) this book should be considered a required read. At less than US$30, it is an inexpensive and practical investment into your on-going education.

Don't settle with just knowing "how" to make your site faster, get the book and learn "why" these steps make your site faster. You'll be a better and more valuable developer for it.
