Expected volatility on TargetingIdeaService Average CPC metric

[j...@clickproquo.com]

Hi,

I retrieved the Average CPC metric from the TargetingIdeaService on April 8th and again, today, April 13th and the ACPC metric showed an average swing of 20% (either direction) with some keywords in the sample showing almost a 100% change.

What is the expected volatility of this metric? How often do you recommend we re-pull?

Thanks,
Jon
