Brand vs. Identity vs. Logo
A logo is the symbol that represents a company, retailer or small business, and everything about it -
how it acts, what it says, where it frequents, and who it's friends are.
A logo is not your brand, nor is it your identity.
Logo design, identity design and branding all have different roles, that together, form a perceived image for a business or product
What is brand? – The perceived emotional corporate image as a whole.
What is identity? – The visual aspects that form part of the overall brand.
What is a logo? – A logo identifies a business in its simplest form via the use of a mark or icon.
