I want to set up CPA bidding for my google campaign. I have imported conversions from analytics. Will CPA bidding work with these conversions - or do they have to be conversions built in analytics?
Re: CPA Bidding
If they're imported from Google Analytics, then yes, they will count towards how CPA is calculated/targeted.
Think of the conversions in the conversions section/page in AdWords as what AdWords uses in this algorithm. Anything that appears in there will be included when calculating CPA and when optimizing automatically for CPA.
Hope that helps,
