As anyone who builds websites will know, search engine optimization (SEO), i.e. optimizing your website & its content to be more readily searched & discovered via search engines, is both deceptively simple in nature yet takes a good deal of time to maintain correctly. Drupal, the CMS system that I have focused my career on over the past four & half years, has many features that give it a leg up in the SEO battle, though in the end the single most important way of improving a site's SEO is by having good content. That said, there are some tools to help improve a Drupal site's SEO capabilities and a new book from Packt Publishing aims to guide you through it. So, how good is it?
