Remove bad reviews from Facebook 

It is generally not possible to completely remove negative reviews or comments from Facebook. This is because Facebook aims to create a platform for users to share their honest opinions and experiences, and removing negative reviews could undermine this goal.
However, there are a few things you can do to try to mitigate the impact of negative reviews on your business’s Facebook page:
Respond to negative reviews: By responding to negative reviews in a professional and respectful manner, you can show other users that you are willing to listen to feedback and try to address any issues. This can help to improve the overall perception of your business.
Encourage positive reviews: By encouraging satisfied customers to leave positive reviews on your Facebook page, you can help to balance out any negative reviews.
Monitor your page regularly: By regularly checking your Facebook page, you can stay informed about what is being said about your business and take steps to address any negative comments or reviews.
It is also important to remember that negative reviews are a normal part of doing business, and it is not always possible to please everyone. Instead of trying to remove negative reviews, focus on providing excellent customer service and addressing any issues that may arise. This can help to build trust and improve the overall perception of your business on Facebook and other social media platforms.
