Taking “control” of your brand isn’t really possible anymore, thanks to social media. Whether you’re in the conversation or not, people will talk about you online, and there’s no way for you to “control” what they say. But what you can do is join in those conversations, and influence them by being a part of them. From negative reviews on Yelp to customer complaints on Twitter, the way to influence your audience’s perception of your brand is to participate in the conversations and steer them in a direction you’re happy with.
