Psychologists understand that the more we are exposed to something the better we remember it. Some suggest it takes 15 or more exposures of an idea or concept before we really accept and understand it.
Keep this in mind when you promote your business or organization. If you want people to remember your company, when they need you, then give them to opportunity to remember you. Do this by keeping your identity in front of them as often as possible within the limits of your marketing budget
