You can build your personal brand no matter what personality you have.
Even without being social.
How is that? By delivering value.
Build a brand is a perception of you. And this doesn't mean you have to be talkative, but it does mean that you have to showcase what you know, and share value to be positioned as an expert.
1. Decide on your niche
Narrow down what you want to build your brand on
Understand who your audience is
Understand what you can offer
Decide on your values
What can you be an expert in?
2. Focus on the audience
Thoroughly research your audience
Know their needs
Know their frustrations
Know what content they react to
Look at the language they use
Know what content they want
3. Start creating content
Get comfortable with creating content
Make it a daily habit
Share what you know
Start teaching
Master the art of writing
Infuse your personality in your writing!
Remember this: you do not have to be social to build a personal brand. But you do need to let people know you exist - by creating valuable content.
Once you decide on your niche, ask yourself how you can become an expert in it. Be firm in your values, and who your audience is.
Study your audience closely and see what their needs are. What do they like? What are they struggling with?
Look at how they consume content and the type of language they use.
START CREATING CONTENT. Share what you know. Don't hold back on giving information!
Build that expertise, build your reputation and create your personal brand.
