Your sales are affected by your guests' positive and negative reviews. You don't want visitors to see negative reviews as they might dislike your platforms and leave. Therefore, you should write keywords that define your main business in a way that shows your positive features, not the negative feedback. Google will not feature them in front of your visitors in search results. Social media pages are authorized by search engines, thus you have to optimize your profile pages with the best keywords that are relevant to your business.
