I don't get asked to review books often, so I was delighted when I got asked to review Drupal 6 Search Engine Optimization by Ben Finklea, it being top of my list of Drupal books to buy. Search Engine Optimization, or SEO, is all about improving your site's position in search results. It's part science, part art, and involves a lot of small, but simple, improvements to your website. An important SEO skill is knowing what keywords to use for your site and how to avoid common mistakes that could have a detrimental effect on your site's ranking. This book does an excellent job at explaining just that and includes great advice and step by step instructions.
The book assumes you're a Drupal newbie, which I was a bit surprised by at first. I wasn't really expecting to see instructions on how to install a Drupal module, but this approach is used throughout the book and is a strong selling point. It takes the magic out of SEO so everyone, regardless of skill level or familiarity with Drupal, can achieve the most from their site.
