Create a writer website or blog. A website not only demonstrates your technical ability, but it also creates an online hub that allows clients to connect to you. Keep the design of your website clean and uncluttered. Include examples of your work that demonstrate the kind of writing you do. Make the samples easy to find and to read, and make it easy for visitors to figure out how to contact you..
Webinars are quite possibly one of the most potent ways you can make an exorbitant amount of money online. You'll need an audience to train and you'll need to know what you're talking about. Of course, this usually requires having a website and some semblance of an online presence. However, people can still do webinars without all of that. For example, you might have a sizable social media following and you train them every week on something to do with social media. But you will need a product to embed and sell at some point. Don't worry about it in the beginning. In my experience, the best webinar platform out there is GoToWebinar.
