(click on image to enlarge)

Comments:
  • Reverse bell curve
  • Scores below 425 correspond to clicks that are clearly unbillable
  • Spike at the very bottom and very top
  • 50% of the traffic has good scores
  • In this scorecard, a drop of 50 points represents a 50% drop in conversion rate: clicks with a score of 700 convert twice as frequently as clicks with a score of 650.
