The duet feature on TikTok can help you reach more people when used the right way. A good way to use it for affiliate marketing is by reacting to or explaining a video that’s already getting a lot of attention. You can duet someone using the product you’re promoting, then add your own comment or show how you also use it. This can make the video feel more real and relatable. Try to keep your reaction short, clear, and interesting so people stay to watch. After that, use the caption or on-screen text to mention where they can find the product, like “link in bio.” Make sure your duet adds something useful and not just you watching silently. That way, people are more likely to trust your content and take action. What kind of duet styles have you seen that worked well for sharing products?
