Payment schedules vary between ad networks. Some pay weekly while others pay monthly. Most often, you will receive a payout between 30 and 90 days after the end of the month when you earned that revenue. When your traffic is low, pick an AdSense alternative with a low payout threshold. That way, you will receive your first payout relatively quickly. For example, Monetag has a $5 payout threshold and a flexible payout schedule.
