You need to drive substantial traffic to your site to generate $300 a day in affiliate commissions. The amount of traffic depends on the affiliate products you promote and their commission rates. For example, if you promote products with a $10 commission, you will need 30 sales a day. If you promote higher-ticket items, you may need fewer sales. To reach $300 a day, you should aim for at least 1,000 to 5,000 visitors per day. You must focus on quality traffic that converts. Consistent content creation and targeted marketing efforts will help you achieve this goal.
