Your brand is what your customers and audience think of when they hear your company’s name or see your logo. It’s what you represent and who you are as a company.

It’s both the voice and the tone within the content you create, and it can be experienced through all the work that you produce.

Style guides are used to define the way the brand will look and keep graphics consistent and uniform across all mediums. Although you'd think you wouldn't need these kind of rules – how to display a logo is really a no-brainer, right? – you really do, and a design conflict moment with a vendor is the wrong time to realize you need to create a style guide so he or she doesn't make a mess of your brand image.

A visual style guide will help the creation and upkeep of your website, app, social media accounts, advertising, marketing, and packaging consistent at all times, and that consistency is critical for brand loyalty in the marketplace. It establishes the rules for fonts, image types, colors, and logo placement.

A content style guide tells your marketing team, content creators, and employees how to write in a way that reflects your brand’s character. It also specifies how you want them to refer to your brand and products, translate industry jargon, and use grammar and punctuation.

An editorial style guide may determine your attitude/personality on social media versus email marketing and your company website.

Having these preset rules of engagement will prevent design snafus and editorial mishaps by ensuring all of your content producers are on the same page.
