CrowdSPRING has published this infographic on small business social media habits. When I first saw the stats on usage, I was a bit taken aback at how low usage stats are for small business. Take a deeper look and I suppose it's no surprise, though. It's very resource intensive to run a successful small business so sustaining a social media presence can be challenging.
That said – it's an incredible opportunity for other folks that run a small business. It shows that there's virtually no competition out there! Start a blog and own your market. Engage in social media and build your audience. It's not going to turn around your business overnight, but it's an investment that will pay off. It could take weeks, it could take months… but you need to engage. If you don't, your competitors will.
