Everywhere you can! This isn’t to say you have to advertise your business or website everywhere, of course. However, you could use your personal brand for:
Marketing materials you put out for your company or blog posts
The products you make, such as books, online classes on Teachable, and more
Your social media posts, especially when interacting with your target audience
Your website’s design. Your brand should influence its aesthetic, theme, and layout in several ways.
Ideally, your brand will feel authentic and as inextricable a part of you as your real personality. In this way, you’ll start to use your personal brand and benefit from it passively without having to think about it.
