As i was looking over our campaign the other day i noticed our CTR % had dropped off slightly from where it had been. I then further looked into the fluctuations of our CTR to the amount of clicks we received each day. I noticed on the lower CTR days we received fewer clicks but that the volatility of the CTR% was much greater than the amount of clicks per day. So after all that rambling I guess I'm asking how precise is the correlation between the two.
