You need to be on every single social network.
Especially if you have limited time and resources, don’t spread yourself too thin by trying to maintain an active presence on every single social media site. Research and learn about the makeup of the audience that populates each social network so you can figure out where you should focus. If your audience isn’t there, don’t waste your time. And as new social networks pop up (as they do all the time), feel free to experiment with them, but be ready to let them go if they don’t work for you, and let your analytics be your guide. We’ve tried pretty much every social network that’s popped up, but some have fallen by the wayside, and we’ve focused our efforts on the networks that continue to generate results for our marketing. Not sure where to start? LinkedIn, Facebook, and Twitter are safe bets. They have huge audiences that span many demographics and industries.
