Example in e-book is bad with very saturated niche, but it may work with less saturated ones.

About payment schedule:
Quote: Our automatic payment cycle is biweekly. Money earned from 1-15 will be paid at 16th-18th and money earned 16-31 will be paid 1st-3rd of next month. If payment days are not a business day, then payout will be send on the following business day. However, if you reach your declared minimum, you can request payment manually - in this case your earnings will be paid within next 2 business days.
