Here are the 10 most read reviews of 2012. Mostly this seems to tell me about the oddities of Social Media, Search Engine Optimization and chance more than anything else. The first two books both were hit by StumbleUpon. I really liked both books, but they far and away had more views than a usual review. The third review was more about SEO. The traffic was almost entirely organic google search traffic. The rest of the reviews were popular but not unusual and all had about the same number of views. The odd exception is Mark Gungor’s book, I am the only one that has a review of it (last I looked) on Goodreads and almost all of the traffic for that book is from Goodreads.
