It is normal to receive negative feedback about your business; it may well be that the service or product did not meet the customer's expectations. Or that they did not meet their needs. But the most important thing is to be able to moderate your opinions in order to bring an appropriate answer to the perplexed Internet users.
That's why it is essential to be on the lookout for negative reviews that may appear on your local page or on social networks. You will be able to verify that this review is legitimate and has been posted by a user who is not satisfied with your services or products. It sometimes happens that people post fake reviews to damage your reputation. By replying to these reviews, you can provide a context that can be useful to users who will look at these reviews. You may also realize that the review is fake, and you can request that Google remove the review. Finally, you can apologize to the legitimately dissatisfied customer, by inviting him to contact you to correct the problem, or by offering him to settle the situation with a commercial gesture.
On the other hand, by responding to negative reviews on Google and social networks, you show Internet users that you care about the quality of your services and products. Responding to negative reviews shows that you take into account the feedback of all customers and that you are doing everything possible to improve your customer service.
