Removing unwanted content or comments from Google can be tricky and is often best handled by a professional. First off, you can try to get the content removed by simply ‘Flagging’ the review. This will alert Google that someone thinks the review is fake, inappropriate, or promotes a competitor. While flagging a review is a simple solution, it is not always very effective, as Google might take time to get back to you (if they get back to you at all).
If flagging the comment doesn’t work, you would then want to contact Google Small Business Report to create a case. Often the representative you speak with will have to escalate your case to a specialist, which takes more time. The entire process is tedious and time-consuming, and unfortunately, Google hasn’t made it any easier over the years. This is why many businesses give up on removing their negative Google reviews themselves and instead choose to hire an agency to handle it.
