I have been fortunate to spend over a year employed by a top 500 Amazon seller as a Marketing Specialist and Graphic Designer. During this time, I had the unique opportunity to work extensively with Amazon's A+ Content system. Sales have been proven to increase on listings that have well crafted A+, so the feature is as invaluable fiscally as it is aesthetically!
I've had the pleasure of taking the lead on several A+ projects for clients of varying sizes, and have gathered some examples of my best performing content.
