Profit refers to the total amount of affiliate profits you can earn through the affiliate marketing program. This includes profit made through pay per click programs and sales. The profit is the sum total of affiliate commissions you make by signing up as an affiliate with a merchant. Affiliates must remember that the total revenue termed as profits is different from the actual net profits made through the affiliate program. You have to spend money on marketing and net profit can be calculated only after subtracting all the expenses from the revenue. Thus the profits promised by the affiliate marketing program could vary from the actual net profits you can make.
