Your brand is the sum of many parts. Your colours scheme, typefaces, your imagery, the language you use and all of the other little details define how the world sees you. How all of these elements combine in your marketing material is key.
How is your business card printed, and what is it printed on. The right materials and format might be fundamental to your brand.
Do you brand social media pages, and do you use the appropriate language for your audience. Branding should be consistent right across the board, not just in printed materials.
