We have been concerned about some fake reviews that some companies have been posting on their page. Some are disturbed if this kind of thing actually would work. I am going to talk about this kind of issue that happened to me with my SEO with my competitor.
This happened when my client was asking me to do some SEO job, and then his competitor would try to cheat so that he can win over me. My client did think that I was working with our competitors. So they had repeated the same cheating over and over again. They filed a lawsuit, but my client won. However, what happened after the issue was worse; some reviews started to disappear.
They would begin to put on their websites lower prices from what is the expected price should be. So basically, when the customer would want to purchase from them because they are drawn to the amount they have put online, they are charged for more. The reason for this is because of the hidden charges from buying such a product.
The effect would be many critics from the people who had been there to buy from them. It ended up people giving up bad reviews to their page, because of how frustrating they had felt during the time. They are now actually breaching their agreement.
Summarize:
Placing something fake and not valid on your designated page can put some adverse effects on your own business, it will serve as a bounce-back on your end. Never try to use this against any other or for your own company. The result will still be reflected in you. You also have to be careful about what you read online so that you will not be a victim of it. Because sometimes fake reviews are made by your competitors to put you down.
