There are no standard solutions here. As an Amazon seller, you can have different priorities. When evaluating a typical Amazon advertising agency, ask questions about how the proposed PPC management/ad management service can meet changing business expectations. You might want an Amazon PPC consultant to help maintain a product’s search page ranking. You might want to invest in Amazon marketing for short-term boosts whereas Amazon advertising management requires an entirely different approach if you want to restrict ad spending and drive search ranking in the longer run. What if you want to reach out to buyers who are searching across parallel/closely-matched product categories?
