Social media provides such a unique opportunity for attracting and engaging with people, and how you use it largely affects which people you'll draw in. That's why it's important to be strategic in your usage, part of which is your stance on incorporating your personal life and views.
I'd venture to say that any confusion you feel regarding the balance of personal/business on social media can be addressed by examining your brand - doing so not only will give you clarity, but will give you a means of measuring any decision you make regarding client-facing changes.
Here are are few things to keep in mind:
Who are you trying to reach? Every business owner should have a very clear idea of whom he or she is targeting as a "dream client." (And if you don't, please consider a business coaching session to figure it out - it'll make all the difference in the world!) When you consider whether that target client would find your social media content appealing - however personal, or impersonal, it may be - you can more easily decide whether you're including the right kinds of posts.
Is potentially turning people off always a bad thing? This can sometimes be the hardest of all decisions, but I'll share with you what I decided for my various businesses: no, it isn't. Not at all. I've found that using social media to share limited commentary on causes that matter to me, or calling out certain political nonsense (Donald Trump, I'm looking at you), was totally in my companies' best interests, as it might weed out people we don't particularly want to work with, while building credibility with those we do. In a similar vein, living and working authentically is one of my greatest personal values, and it's important to me to be myself in everything I do, including social media. That doesn't mean I put everything out there on my business accounts, but if someone's going to clutch their pearls over the fact that I have quite a few tattoos or that I love a good happy hour, those aren't my people and that's okay with me.
What types of social media are available to you? When you have personal, private accounts as well as business accounts, you may find it's easier to balance your content - sure, you can let a little personal flavor into your business posts, but you can also save the really personal stuff (the most ridiculous selfies, roadtrip recaps, whatever) for your own accounts. I myself use my personal Instagram for that kind of thing, and restrict access pretty heavily; then I'm a little more conservative with my personal Facebook and Twitter, and then use my many business accounts for the professional posts. It works for me, but I could see that being more challenging if someone were relying on just one set of accounts for the many purposes of social media.
What feels right? This is a good question to ask yourself in pretty much any dilemma! When it comes to social media, however, think about what kinds of content feel good to you to post, and which make you feel a little apprehensive about how they'll be received? (And if you feel like your current brand is no longer in alignment with your values and your vision for your business, remember that it's never too late to make changes!)
Something we always take into consideration when creating social media content for our Firebrand Messaging clients is how personal they want their posts to feel. When you're handling it on your own, just consider the questions above, and your usage guidelines will come into focus.
