No. 4: You don’t post often enough.

Facebook and Twitter might be the big boys, but people read news on LinkedIn, too. And, while Google+ might not be racking up a ton of active users, if you’re on there, you should at least share something every now and then. The point is don’t leave your profiles barren.

So, pick a schedule: maybe three to five times daily for Facebook and 15 minutes a day where you line up all your tweets using Tweetdeck. And check back regularly to see if people have responded or shared your posts. An application like Twunfollow can give some indication of whether you are annoying your audience with irrelevant content. And, whatever you do, don’t cross-link your feeds. Each platform has its own needs and different audiences.
