Hello & Welcome
I assume you are referring to online customers vs offline that you meet face-to-face? My first suggestion would be to use your name - even if its a pen name, people need to know who you are and how to address you.
Your post here is a good example - an introduction, but no name - just for example.
Even on your website there is no About page or Profile that tells us who you are and why we should do business with you. Your contact page lacks that as well - I have no idea who I am contacting.
I would recommend adding a name, a photo, and a bio or profile page.
Once you do that, your next step will be to keep all communications personable. Show your genuine interest in assisting your clients with their projects, etc.
