The whole purpose of marketing is to educate your audience and stay memorable until they are ready to buy from you.
If you think back, you probably still remember brands and their messages from many years ago. All because they were in front of you many times, and they had a compelling message. For instance, Minstrels - The chocolate that melts in your mouth, not in your hand. A campaign from Galaxy that saved children’s stick fingers and made Minstrels unique chocolate treat.
Increasing the number of times your brand and message is seen is vitally important. As any message needs to be seen many times to cement in your clients and prospects minds.
