To figure out if an affiliate product has good demand, start by researching what people are searching for online. Use tools like Google Trends to see if the product or its category is popular. You can also check marketplaces like Amazon to spot trending items or read customer reviews to understand what buyers like. Another way is to look at social media platforms to see if people are talking about the product or similar ones. Pay attention to how often it's mentioned or shared. Also, consider the product's niche; some niches, like health or tech, often have steady demand. You could check affiliate networks like ClickBank to see how well similar products are selling. Testing a product with a small campaign can also show you if there's interest. It's all about understanding what people want. What are your thoughts on this?
