As part of your PPC management, it's best to be aware of the cost of each ad format. CPCs can range from $0.02 to $3 while the average cost is $0.35. But it can go beyond that and vary based on your chosen ad type, product category, and marketplace (demographic target). You can bid for sponsored product ads, brand ads, and display ads for as low as a few cents. Meanwhile, audio and video ads are the most expensive. Amazon pegs the minimum budget for audio ads at $35,000 as they're sold on a cost-per-thousand impressions basis. Such ads will also require coordinating with an Amazon Ads account executive.
The superstore also says that a budget of $10 daily will be enough to boost sales, but it will be wise to take the advice of seasoned marketers on Amazon marketing services. This includes calculating your average cost of sale or the amount you spend for production, overhead, and others to obtain leads when planning your PPC campaign.
