If you are serious about your marketing, you probably already have a copy of The New Rules of Marketing & PR in your library, but the 3rd edition, The New Rules of Marketing & PR: How to Use Social Media, Online Video, Mobile Applications, Blogs, News Releases, and Viral Marketing to Reach Buyers Directly, updates the book to include more social media areas and content.
Even if you have an older edition, the core tenets of this book can be applied to your 21st Century marketing plan, but I’d recommend picking up (or downloading to your Kindle) the latest edition.
If nothing else, grab this book for the updated case studies, examples, and the Marketing and PR Strategy Plan template.
