China has become the world's largest e-commerce marketplace and will soon be home to more ad spending than any other country. With e-commerce representing about 20% of all retail sales in China it's to be expected that this market segment will draw significant attention by government regulators. How do global brands and their advertising agency partners navigate this complex and ever-changing landscape? What patterns have begun to emerge that will help increase the effectiveness of their advertising? How, when and where do we engage this large and growing base of online consumers? Answering these questions correctly will be the difference between gaining market share or seeing diminishing ROI performance. This survey, while far from exhaustive, brings together research from a large number of sources in an effort to educate, challenge and stimulate. A special THANK YOU to companies like We Are Social, McKinsey, Bain, CIC and the many others from whom this data was obtained. China's digital and e-commerce landscape is still being defined and it's not a market to enter unprepared. It is big, complex, changing and unique. But it can be won with the right combination of talent, resources and strategy. Good luck to all who would enter!
