Earning money online can be done in a variety of ways, but some of the most effective strategies are freelancing, affiliate marketing, and selling digital products. Freelancing involves providing services to clients on a freelance basis, such as web development or writing articles. Affiliate marketing is when you partner with another company and promote their products or services in exchange for a commission. Finally, selling digital products is when you create a product once and monetize it multiple times by selling it over and over again on the internet.
