AAhmet, founder of radarzon and MEVLYS
Every time a competitor ran a Best Deal, a Lightning Deal, a Voucher or a Price Cut, I found out five or six hours too late, and I lost sales in exactly those hours.
I sell on amazon.de myself. And it was never just one competitor. It was not only discounts either: competitors went out of stock, came back in stock, their review counts moved, and I learned all of it late. Knowing these things early is an edge. When a competitor runs out of stock, that is your window to push. When one passes you on a keyword, you find out the same day and raise your PPC on exactly that keyword to push them back down. I realized there was no system that let me react this fast across all of my competitors, and that reacting fast was exactly what pushed my keyword rankings up and kept my position strong. That is why I built radarzon. You hear about every move when it happens. And every evening, the Daily Rank Report shows you how your competitors closed the day on the keywords that matter, compared to you. radarzon keeps pushing you toward the next action, so you never lose ground.
