Many services claim they can, but we cannot vouch for this or have we needed to try, either for ourselves or our clients. Negative reviews can harm a business. It can be used against competitors to damage their online business profile, but this is highly underhanded and not recommended.   However, if you receive real negative feedback, it would be wise to deal with it, just like you would face. Be sincere and offer a resolution, and thank them for letting you know. For example, it happens a lot in food establishments—poor service, poor meals, etc. Take the feedback onboard to address the issues in-house. If the reviews are fake, there are possible methods to have them removed.   Just Googling, we found this blog post How to delete negative reviews and outdated content on Google.
