It is difficult to determine which of the 10 tips is of greatest importance. I would say that you want to consider all of the points, and simply make sure your bases are covered.
The industry is growing quickly around us, and one thing that is becoming a greater and greater need from clients is that of reporting. They need to show that their dollars are being well spent. Metrics and the development of field metrics is something that separates many companies from the rest of the pack. That is the business side of things.
From the perspective of execution, appearance, messaging, enthusiasm and the 'call to action' are all very important in creating a compelling, memorable brand experience.
Good luck out there. If I can be of assistance, drop me an email or a call:
