The number ONE barrier to a successful online ad campaign online is not a lack of budget or poor advertising, but a Website that doesn't convert visitors into customers. Creative is critical to success. Yet far too often we see clients invest a great deal of funding into advertising but budgeting very little when it comes to their site or testing and improving their back-end conversion process. This makes no sense to us because the Website plays such a major role in whether you're going to generate customers, how many, how often and at what cost. It's the advertisement's job to stimulate interest. Your Website and sales team close the deal. Good creative and a good site are critical.
