Make sure you post on all of the social networks

Much of the focus of small businesses is on Facebook and Twitter. And that's a great place to start. You can see through how many businesses put a sign in their window that asks them to follow them on those sites, how many national brands are advertising their Facebook page in their Super Bowl ads, or even how many sites you can buy Facebook likes at to see how important and how much emphasis people are placing on the 800 pound gorillas in Facebook and Twitter.  

But don't ignore things like YouTube, Google Plus, LinkedIn, Pinterest, Instagram, Yelp, and many others as well. Just the search engine benefit alone is meaningful, but it also helps you find more customers you might not have been able to reach. Some portion of the population aren't active on Facebook, but are active on LinkedIn for example. Or maybe some people decide that Facebook isn't for them because of privacy concerns, but they love posting on Pinterest. If you want to try and reach as many people as you can, you'll try and develop many different social pages and see what works best for you. It's not necessarily too time consuming to do this. There are some types of social media management software that can allow you to post on multiple social networks with just one post. Or through various sites' APIs you can even make your own custom solution.

Having a primary focus on Facebook and Twitter is certainly wise and a valid strategy, but don't forget to look and see what other options are out there because every little bit can certainly help you out, particularly when you are a new business and just starting out and need every advantage you can get.
