关于CB的产品中grav的指数解释
grav这个指标到底是怎么算出的?
是8周前的数字还是到现在的
我被搞糊涂了,到底反映了什么指标呢?
这个数字大好，还是小好
高手指点下 Gravity: Number of distinct affiliates who earned a commission by referring a paying customer to the publisher's products. This is a weighted sum and not an actual total. For each affiliate paid in the last 8 weeks we add an amount between 0.1 and 1.0 to the total. The more recent the last referral, the higher the value added.
过去8周内每个affiliate卖出一个产品，Gravity就增加0.1-1.0，近期越多的affiliates卖得越多，Gravity增加值越大
越高说明affiliates卖得越多，其他可参考[url]http://www.ccbbs.com/viewthread.php?tid=9883&highlight=grav[/url]
