After all what you look like has no bearing on your ability to do your job and deliver your services.
Think again. You're representing your small business and possibly starting from scratch. You go to those all important business networking meetings and make a whole bunch of useful contacts. You hand out your business cards with all your contact details. You've probably collected a few yourself. Well so has everyone else and your card and details are in amongst them.
What do you do when you get back from that meeting with all those business cards? I sit down and look at the websites of the people I've met and I look at their various social media profiles. At this point, I sometimes find I'm having trouble matching the faces I've met with the details I've collected and this is where a photograph on a website or social media profile is essential. I never forget a face and I have been to many networking meetings where I've recognised the face of someone I've met before, but can't quite remember how or what they do. With this in mind the photograph really helps lodge that person I've just met in my memory.
Having a photograph on your website is one of the many small things that can help when trying to stand out from the crowd of the many others who are competing for your potential clients.
On the other hand your potential customer could have come across your website and got in contact with you. The next step is usually that all important first meeting. If you're a small business working from home, the chances are this meeting will be in a public place and not at your home. If nothing else that photograph helps your prospective client identify you and saves the embarrassment of accosting strangers in a coffee bar. I've done it!
