You are a small business. You sell products or services that I'm interested in and I'm ready to become your best customer! And then I notice a few things and look for someone else in your field. Even if you have customer service down to a science, there are things that make me walk away.
1. Do not load your feed with political or religious posts. It's okay to have an opinion, and even to share it occasionally in a respectful manner, but remember you are talking to your customers and many of them may not share your views.
2. Do not badmouth a customer. Ever. Seriously, other customers are reading this and wondering what you are saying about them. Is it worth a two sentence rant to lose even a small percentage of your business?
3. Do not complain or whine or gripe about your lack of sales. When I see that, I just assume that everyone else knows something I don't and join them in steering clear of you. While we're on the subject, don't post sob stories about why I have to buy something from you because you need the money so badly. We all need money to get by in this world. If your kid needs braces and you whine about how much you need to sell because of that, you may just remind me that my kid needs braces too, so I should save my money.
4. Do not write a blog post about how to sell the stuff you don't like, at your top price, to a group of people that you consider less important than your real clients. You think I'm joking? I've seen this! Some of us treat every single customer with the same respect and work hard to give them our top products. Customers do know the difference.
5. Do not make me try to decipher what you are saying. DO use proper English, and check your spelling and grammar. Also, I don't want to see how many swear words you know, or how many creative ways you can use them. If you can't shout it in a room full of grandmas, don't say it online.
Your name is inextricably connected to your business, so even if you post these things on your personal pages your customers know, and despite what you may think, they probably care. Stay positive and respectful, it makes the difference between success and failure.
