Reviews software company PowerReviews has released an interesting infographic sharing some in-house data that illustrates that every review shared on Facebook generates $15.72 in sales, that 70% of reviews shared to Facebook generate further interaction in the form of comments or likes, and that Facebook shares generate 5x more shares than other social sharing.

How PowerReviews calculated this RPS – revenue per (review) share – is here, along with a downloadable calculator (here) for estimating the value of a review shared to Facebook.  According to PowerReviews calculations, for every 12 reviews shared on Facebook, you make one more sale.
