From this, you would have understood that the rivals in your business can harm you with uploading wrong or bad reviews & buyer guides on the internet. Before buying the product the customers will tend to read the buyer guide and will try to operate the product according to that. This will not yield any results and your genuine customer also will give negative feedback about the product. A fake review is contagious like an epidemic. In the customers who read the reviews, more than 80% of the people believe what is written online. So you have to be careful about the fake reviews and buyer guides available online.
If you are the owner of the business you have to monitor these numbers always. A business that has the rating more than 4 will be accepted by more than 90% of the customers. If your product is available online the number of reviews and rating will affect the sales and visibility of the product. When the customer searches for the product online a better number will give better discoverability.
