If you've never done any kind of internet marketing, but you're interested in starting, it can be hard to find the best foot forward because it seems like there is always so much to do and to get done instantly that it can be hard to prioritize.
Your brand is everything when it comes to your business, and your business is not your brand. Your business is what you do professionally to earn money, and your brand is much more. Your brand is a mix between yourself, and what you're selling - be it a product, service, or information. Your brand is the best parts of yourself, combined with your businesses core values, intent, and purpose.
