Do you know when your first impression is? It is not when your potential client(s) reach out to you. It is not the first time you speak to them. And it definitely is not when they decide to hire you.
It is when you are networking, responding to other peoples posts, what you say, how you come across to them, & how they interpret what they see.
This is what drives them to either stay away or reach out to you and want to know you more. It's not all about being professional, but being personable.
People generally connect on a visual level; so what image are you giving them?
You must be honest & up-front with them. You should appear organized and well informed on what you are offering; and if you are new to it again be honest about it. This will build a better relationship and most people are understanding.
Make sure your Social Media platforms are well organized and personable, as well as personal so they will be more comfortable to work with you.
Presentation, Presentation, Presentation.... What is your image?
