3am EST time tomorrow I'm resuming some campaigns and was wondering what I should set each budget to. Each campaign has 3 ads (replicated the same ad 3x) and currently the budget is at $10 - is this good for testing purposes for one day?
per ad as opposed to per campaign?
Err yeah per campaign I meant, but only 1 ad per campaign 
if you can keep an eye on them, i would set lower to $3 or $5. usually only one will take off. and if you are watching it closely, you can pause the other 2 before they take up too much of the budget.
