There are tons of social networking sites out there. There’s Facebook and Twitter, of course, at the top of the ladder, with Google+, Instagram, Pinterest and others below them, and a number of smaller, more specialized sites below that. If you want to succeed in marketing, having a social media presence is essential. But where should you focus that presence? Even if you have a fulltime social media guru on your inbound marketing team, whose sole job is to maintain all of your social networks, there are just too many to cover them all effectively. Social networking is about personal interaction and communication with your followers. The more networks you have to juggle, the less time you have to spend on them individually, and the more impersonal each one becomes.
