What is the "PowerRanking" and "EPC" for products in the Digital River Affiliate Network interface?

在Digital River代销商网络界面上的产品PowerRanking和EPC是什么?

The PowerRanking gives affiliates a relative measure of the commissions paid by a vendor for a product in the Digital River Affiliate Network. The measure is based on the level of commissions paid by the vendor for that specific product within the last 90 days. The more bars in the PowerRanking, the more commissions that the product has generated for affiliates in the network during the last 90 days. PowerRanking 是为代销商针对发行商的产品透过Digital River代销商网络销售所支付的佣金数额而提供的一个评量。评量标准是基于发行商在过去90天内对特定产品所付的佣金高低程度。PowerRanking 里的横杆越多，表示该产品在过去90天内为代销商网络带来的佣金就越多。

The PowerRanking bar comes in two colors. Green indicates a product that has been in the Digital River Affiliate Network for more than 90 days. Gold indicates a product that has been in the affiliate network less than 90 days. PowerRanking 横杆有两种颜色，绿色代表产品成为Digital River代销商网络产品的时间已超过90天，金色表示产品成为Digital River代销商网络产品的时间少于90天。

EPC, or earning per click, is the measure of "productivity" for the product within the Digital River Affiliate Network. EPC is calculated by taking the commissions generated by the product and dividing it by the number of clicks tracked for that product within the Digital River Affiliate Network. The higher the EPC, the more the product pays out per click. EPC或每个点击的平均收入是衡量产品在Digital River代销商网络的“生产力”。EPC是以产品带来的佣金除于Digital River代销商网络中带来的点击数量。EPC越高，该产品的每个点击获得的收入越多。

EPC can be affected by many things including commissions, the type of traffic driving the sales, the vendor¡¦s commitment to supplying good creative and wrapped trials within the network, etc¡K EPC is meant to be a general measure of the productivity of a product to generate commissions for an affiliate. 影响EPC的因素有很多，包括佣金多寡、带来销售的流量类型、发行商是否尽力为代销网络上提供有创意的产品图像和内容和提供试用产品等等。EPC是衡量产品为代销商赚取佣金的生产力的一个评量标准。
