Practical insights from practitioners, from fighting the gray market to pricing competitively
“Our products keep ending up with unauthorized sellers. We can’t find the cause, and there’s nothing useful to go on.”
“We’re losing sales to the competition for Item Winner, and we don’t know where to start.”
“We do price monitoring internally, but we can’t really tell whether it’s working.”
If you run e-commerce, you’ve probably asked these questions yourself. Once a brand’s pricing policy starts to break down online, the problem of unauthorized gray-market sellers only gets worse.
So how are brands tackling it? To find out, MarqVision surveyed 200 e-commerce practitioners in Korea and abroad. Our insight report draws on their experience to show how serious gray-market revenue losses are and what strategies actually work.
