Before anything, the first step is to join an affiliate program or network. Popular networks include Amazon Associates, ClickBank, and CJ Affiliate. Once you sign up, browse the products or services available for promotion. Select the ones that fit your niche or audience. After choosing a product, you’ll be given a unique affiliate link to track your referrals and sales. Some programs offer deep linking, which allows you to link directly to a specific page or product. You can also find affiliate links through influencers, bloggers, or websites that share affiliate products you may want to promote.
