A great cover of G+ fundamentals for individuals, less valuable for businesses
on 16 June 2013
The book entirely focuses on Google+ for individual users, going from the most basic functions that are available. Now, it will be an incredibly useful guide for people who have heard about Google+ but never checked it out, but it might provide less value for the others. From a business perspective, I wish there was more details on how Google+ impacts today's businesses, especially from the SEO perspective: adding a chapter or two about Publisher/Author tags, the idea of Page Rank for G+ profiles and how that affects affects search results, and, ultimately, how Google+ can help businesses get more discovered (and profitable).
