Content Rules is a good read, written in a style that suits the online world the authors are talking about. The authors present ideas and concepts in a straightforward way, including some real-world examples of how they personally discovered what works, and what doesn't. They also provide links to websites, blogs,etc., that provide additional examples of what works, or sites that serve are further resources to explore. I found that after reading a couple of chapters I would have to log on to explore these links and bookmark the ones that fit my areas of interest. The authors also have their own website, which often has updates or further information that is useful. For a hardcover book the price for this title is reasonable, and I've already found myself pulling it off the shelf to refresh my memory of something in it.
Aside from being an inherently fascinating subject to a Marketer - Handley and Chapman filled the book with a good balance of statistics on Marketing on the web, provides many great use-able ideas, and includes several real world case studies at the end. Part of the challenge of Marketing on the web, is not necessarily knowing what is the correct approach. Do you give away the content, or must you always capture the requestor's vital information for a future eblast campaign. Content Rules gave me some good and balanced ideas in this regard. The answer is a bit of both. Sometimes you want to be a thought leader, and provide free content with no strings attached. Yet other times you will want to do an exchange... and better yet a growing exchange.
My favourite part were the case studies of HubSpot, Qvidian, AskPatty.com and Indium. These were exceptional as they come from real companies, contending with marketing on the web, using content marketing - and doing so in a unique manner.
Handley and Chapman wrote an excellent piece. Well recommended read!
