"I have this photo of me and my dog that I really want to post to my (business) website – it's such a great photo"
"Can I post my wedding photo?"
"How about this photo of me playing softball?"
There's a fine line between your business and your personal life, especially when you're an entrepreneur running a one-person business. So, where
I know this is not definitive, but where you draw the line depends on 3 things:
1. The way you run your business. This speaks somewhat to the level of crossover that you want between your business and your personal life – if you want to have a private side of your personality, and then a public face of your business, be careful about how much you expose on your business website, blog or on your outgoing emails.
2. How much you want to position your business for growth. If you want to grow your business so that there are other service providers (employees, consultants) in your client-care pipeline, then you may want to withhold putting too much personal information on any of your marketing materials. That way, you can later hire more people and wean your clients off of any expectation of interacting directly with you as your business grows.
3. The way you want to present your brand. Whether or not you're personally involved in your business's brand depends partially on how you want to present the brand itself – and what your clients want to see. If you're running the type of business where your clients, by and large, want to interact with you on a personal level, then it might be best to go ahead and let some parts of your personal life cross over to the business side. But, if your clients would prefer to just deal with your professional side, then it might be better to keep your personal bits to yourself.
In any case, if you do choose to publish any personal stuff on your website, do explain it, and try to create an explanation that weaves the story behind the picture in with your business story. That way, you can help to make the whole presentation make sense – whether or not your client wants to hear the personal stuff, you want it to make sense as to why it's there.
