Creating brand continuity is key to building top-of-mind awareness which can lead to brand preference. It should start with the company logo and, when dealing with a family of companies, continuity across logos can help to expedite unifying public image. At AMN we unified the brands with a common bug, color palette and endorsement lines.
At EmCare, we utilized strong visual elements, colors and messaging across all our various marketing and media channels in order to achieve cohesive branding across all five of EmCare's service lines.
Even pulling our brand's continuity through to our social media channels - Facebook, Twitter, LinkedIn, etc. - helped to emphasize brand cohesion.
