There is no one good answer and I agree with CentennialEmpire that it all depends on where you are with AdSense. As an executive for a firm that makes six figure income with AdSense, waiting for 30 days is out of question. Actually, we monitor the data on 2-hour intervals to plan our strategy. But if all you make is a a few bucks a day I agree that once a month makes perfect sense.
