My approach to developing, organizing and maintaining PPC structures is based on the MVP principle (minimal viable product), I specialize in organizing campaigns in such a way that I can quickly and cost-effectively identify opportunities for growth or lack there of. What end up happening over time is that any ASIN under my management will reach it's "natural" position on Amazon in terms of sales volume.

Additionally, as the structure matures it becomes more flexible and able to easily adapt to market tribulations. A mature PPC structure can easily adapt to a plethora of market conditions while maintaining cost-effectiveness.
