Like Georgie Lowery said; book reviews don't bring in a lot of traffic, in general. When I first came here, I published a bunch of them, but I quickly realized that every book has a slew of reviews handily available on websites like Amazon and Barnes and Noble. So, it seems unlikely that someone would seek out reviews beyond product pages. I do think they have a place here, but I think they need to be disguised. For example, my 'reviews' of Harry Potter and the Hunger Games generate more traffic because they focus on the popularity and controversy, which goes beyond a review into a more critical analysis of the book's impact. Essentially it all boils down to giving the reader something they can't read anywhere else.
