Promoting affiliate links without paid ads takes creativity and patience. You can start by writing blog posts that answer questions people search for, like product comparisons or honest reviews. On social media, you can share short guides, explain how something works, and naturally mention the product. Email marketing is another good method; it lets you share helpful tips while linking to products that fit those topics. You can also post in forums or communities where people are already interested in what you promote, but without spamming. Consistent, helpful content builds trust, and people are more likely to click your links. What other free promotion methods have you seen that seem to work well?
