You probably use social media to get new business and interact with current customers. So most corporate social media accounts have a fair dose of self-promotion. That’s fine, and people expect it. After all, they’re likely already fans of your products or services if they’re following you online. And people are used to corporate and professional accounts posting promotional items.
The problem comes in when all you ever do is post self-promotional updates. It’s the equivalent of email spam, and adds little or no value for your followers and fans. In a lot of cases, you’ll alienate your current customers and they’ll unfollow you.
Think about the kinds of content your customers are likely interested in. Then post about those topics, with useful links to things not directly related to you or your company. This kind of content adds value to your followers, and may result in getting followers that aren’t necessarily customers or fans of your company.
