Advertise from multiple angles
As mentioned above, it’s good to test multiple marketing channels and ideas to see what works best. Often, it’s not any one thing but a combination of all of the above. When your customer hears you on the radio, sees you in a search engine result, and then finds you mentioned in a blog they like (content marketing), they start to accept your brand as a solid, dependable, known entity. They may not have the need for your product or service immediately, but when they do, it will be your name that comes to mind instead of a competitor’s.
