Many times i research internet for some products or just looking for something that i need to research. Many websites who selling some kind of services or products display "customer's testimonials" and all of them are always so positive
However, to be honest, these testimonials look so fake to me, then that falseness turn me away even if they have good product or service. I discovered many times fake testimonials by fake imaginary people. But also i have seen fake video testimonials which I KNOW have being bought from Fiverr or similar marketplaces.
I am not sure if visitors and potential customers trust these testimonials, but honestly i don't and after my experience i don't eve bother to read them. For me it's complete nonsense and i can't trust them any more even if there is few real testimonials.
