If Blended CPA is < "X" over last 7 days then raise Facebook Budget by "Y" - do this Monday, Wednesday, and Friday at midnight
X = (Blended CPA target) - 5% to 10% (each advertiser can set this to a static benchmark) Y = 50% of X
ie: if Target CPA is $50 and allowable variance is 10%, then the rule reads... If Blended CPA is < $45 over last 7 days then raise Facebook Budget by 5% - do this Monday, Wednesday, and Friday at midnight
If Blended CPA is > "X" over last 7 days then lower Facebook Budget by "Y" - do this Monday, Wednesday, and Friday at midnight
X = (Blended CPA target) - 5% to 10% (each advertiser can set this to a static benchmark) Y = 50% of X
ie: if Target CPA is $50 and allowable variance is 10%, then the rule reads... If Blended CPA is > $55 over last 7 days then lower Facebook Budget by 5% - do this Monday, Wednesday, and Friday at midnight
If Ad CPA > "A" & spend is > "B" over last 7 days, turn ad off
A = Target Platform Specific CPA + 10%
B = Target Platform Specific CPA x Average Daily Conversions for Campaign
If Ad spend < "C" over last 7 days, turn ad on
C = B / 10
ie: if Target CPA is $50 and the campaign average 20 purchases a day then the rule reads... If Ad CPA is > $55 & spend is > $1000 over last 7 days then turn off ad
If Ad Spend < $100 over last 7 days, turn ad on
