Be Social on Social Media

This should be a given, but if your band has a social media account, you should actually be “social” on it. You should really try to use each individually and understand how your fans interact on each one, but even if you absolutely must sync the accounts (so that updating one updates them all), you should at the very least check for comments or replies on each. If your fans reply to you and try to interact with you and they’re constantly ignored (because you actually posted it from a different service), eventually they’re likely to stop trying, or stop following altogether.
