我观察了从位置1到8的平均点击率(递增为0.1)，得出每个关键词的质量分。
I then looked at the average click through rate in each position from 1-8 (in increments of 0.1), for each keyword Quality Score.
如果你的广告排名为4，平均点击率为4.5%，那么你的广告质量分应该为7左右。
If you have a click through rate of 4.5% in position 4, you should have a Quality Score of around 7 or so.
基于上面的理论，你可以预计下面各个位置的平均点击率，以及了解它们如何被转换为质量分？
Based on these fitted lines, you can estimate the following average click through rates by position, and how they are converted into Quality scores.
