A brand identity is one overall, solid image that the business presents itself to the public. It helps the brand develop its own unique presence and differentiates itself from others in the market. It's a digital rulebook that specifies every aspect including the look and feel of your brand, which can be used internally while building and creating a company culture and typically shared with partners, media, agencies, and with your teams to brief them on how to communicate your brand properly and consistently.
Branding includes logo design (tells your story/face of the company), branding style guide, which includes logo, fonts, and typography, logo usage/image guidelines (including on social media), tone of the business, color palette/representation with descriptions and brand board.
