Affiliate marketing tends to generate more income per visitor because you earn commissions on sales rather than small payments for ad clicks or impressions. However, ads are easier to implement and provide a steady passive income stream if you have high traffic. If your blog receives a lot of visitors but they don’t engage much with affiliate links, ads might be a better fit. That said, the most effective monetization strategy usually involves combining both. You can run ads on your site while also including affiliate links within your content. This way, you’re maximizing your earning potential from both approaches.
