Many people rely on review sites, such as Yelp. The problem is wondering whether those reviews reflect a true experience with the business.
In my analysis of Hertz Downtown Portland, of 64 reviews from 2015 forward, 13 were positive. Were these real or fake? Looking at the stats, there are very few reviews with 2 – 4 stars. They are either in the 1 star or 5 star range. That in itself is suspicious. Were there people who just happened in at a good moment, or were they paid for their reviews?
