Video reviews show products in action and let people see how something actually works. Written reviews explain details through text and images. Some buyers prefer watching because it feels more real and saves reading time. Others want text because they can scan quickly and find specific information faster. Video takes more effort to create but may stand out more in search results or social feeds. Written content is easier to update when product details change. Both methods can work depending on the audience and product type being promoted. Which format brings better results when promoting affiliate products to different audiences online?
