You don't always need to pay to promote affiliate products, but spending money can help you reach more people. Free methods like sharing on social media, writing blog posts, or creating YouTube videos can work if you have time and skills to build an audience. These take effort and patience to see results. Paid promotion, like ads on Google or social media, can get your links in front of people faster, especially if you're targeting a specific group. The downside is the cost, so you need to balance what you spend with what you might earn from commissions. Start small if you choose paid ads, and test different platforms to see what works best for your products. It depends on your goals and resources. What's your take on this?
