Try an average daily budget
of at least three times your CPA or cost per conversion for the conversion
actions selected for your campaign. Generally, the budget should be consistent
with other well-performing campaigns in your account.

If a budget is too low relative to the CPA or cost per conversion, you might
see a slower ramp-up period or fewer conversions over several days.
