Avg. CPC is higer than (Max. CPC * BidModifer)

[Jay Zou]

Hi,

I set Max. CPC to 7.00

Then using BidModifier I change the bid by +5%. Which will make the Max. CPC to 7.35 right?

But with 1 more click added on, now my Avg. CPC is 8.01.

Hi Jay,

If you have set more than one bid adjustment in your campaign, those adjustments are typically multiplied together to determine how much your bid will increase or decrease. This might be the cause for the higher Avg. CPC value. You can retrieve existing bid adjustments using CampaignCriterionService or AdGroupBidModifierService as described here. You can find more information about bid modifiers here. I suggest that you post this question in the AdWords community forum as they are better equipped to answer this query.
