Curiously, the value next to the "Reputation Trend" label is also "Reputation Trend", clean linked to the same business at JB. I don't think these pages pass PR.
I see this kind of data supply arrangement as a good way for an IYP to get some of the LBC action, if they missed out being the supplier of primary data.
Reputation trend seems like a very good tool. One of my clients bought an existing business that had poor reviews in the past. Their historical review average is kinda poor but their trend clearly shows the new owners are great.
btw, Judys Book is one of the original review sites. They blew thru some dot com money, crashed, burned & then relaunched about a year ago. They're a strong citation source in the industry I follow most closely.
