Affiliate marketing is one of the quickest ways to start earning from a blog because you don’t need to create your own product—you can start recommending products from day one. Selling your own services, like consulting or freelance work, can also bring in immediate income, especially if your blog showcases your expertise. Launching a simple digital product, like an eBook or an online course, is another fast-track method. You can create and sell these products directly to your audience while continuing to build your blog’s traffic.
