The first step in using your voice as a business tool is to establish your expertise. You need to establish yourself as an expert within your niche. That is the only way your audience will take your words as an authoritative resource.
Dive into your skillset and find the area that you believe is your strongest field. What can you offer that no one else in your industry can?
Once you’ve found the place where you can set yourself apart from the rest, target in on that. Create useful and educational content surrounding your expertise. Write about things no one else besides you can write about, and find the questions no one has answered yet. By doing this, you will start to gain traction and attract a significant audience.
