B2B brands often become inconsistent in organizations that lack guidelines governing brand usage by internal users (marketing, channel partners, direct sales) and external providers (e.g., agencies). The result is a similarly discordant set of messages delivered to external audiences. This problem can be addressed through the creation of a thorough marketing style guide to ensure that marketing content creators (including agencies and freelancers) are consistently on brand. This report illustrates a best practice style guide that will enable marketers to do their jobs more consistently, effectively, and productively.
