I find it hard to believe that a person who had something negative to say as I pointed out above, would give a company 5 stars.
Simple mistake. After all: Why would someone fake a positive review and then write a negative comment in the comment box? Customer clicks the wrong number of stars, and submits. One of my competitors started to encourage his customers to review his shop shortly after we started to do that. The fifth review is: Everything perfect! Rating: One star. - Bad luck.
And the reason why so many reviews look the same is simple: Customers do not know what to write in the comment box and then check previous reviews and write the same.
Of course there are fake reviews. Not always posted by shop owners though. I know of at least a dozen reviews about my shop which are fake. They are positive but they have most definetly not been posted by customers. And not by me either. But by the guys who run the review platforms to make it look more busy than it is.
