#10: Enhance learning

Scents can even make learning easier. If your company is holding an employee training session or a customer workshop, consider a blend of scents such as rosemary, sage and basal, which stimulate concentration and invigorate mental activity.

Takeaway: With $200 million in sales (2013 figures) and a predicted annual growth of 10%, scent marketing is coming of age. However, many businesses have yet to take advantage of this new marketing touchpoint. If your business could benefit from increased profits, stronger brand loyalty and customers who are more relaxed and happier, consider scent marketing. It just makes sense.
