At its core, branding is who you are.
Marketing is how you build awareness.
You can’t compare apples and oranges, they’re just not the same thing and either is branding and marketing.
To sum it up; Branding is the reason someone buys. Marketing is the reason someone thinks of buying.
You can’t market your way out of poor branding.
If you have a business you already have a brand and your customers are having a brand experience. When they interact with you, your website, your social media channels, your products, services... this is their brand experience. So, if you're not strategically branding your business it will get branded for you!
