There are many types of customers and just as many reasons for buying a product. Getting Brand Awareness into peoples minds is no small task.
Taking steps in the right direction , IMO ,
Repetition in the ad, and repation in running many ads.
Can't hurt, any PR is good PR,
But we can learn form mastakes only if we do SOMETHING.
The problem with doing NOTHING,
is you do not know when you are done.
