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. 

Blogging is still a viable online business idea, and one with as much potential as ever. Just make sure that you start a blog on something that people actually want to read about. If that happens to be something you’re passionate about that’s great. But you need to understand that it’s way easier to monetize a blog about organic dog food than it is to make money from a blog about obscure literary fiction.
Choose your niche and check for demand: The golden course combination is when you can find an in-demand niche that aligns with your skills and unique experiences. A great way to do this is to use Google Trends, Google’s Keyword Planner and other key blogging tools to do keyword research and look for average monthly search volume for keywords related to your proposed course content. Are people actively looking for high-quality information about this subject? Of course, if you’re already creating content for a blog, coaching service, or a site like Medium, you can test demand this way for free just like Bryan did.
Regardless if you need to earn some fast cash or we're just talking about making money in the grand scheme of things, there's an important psychology that needs to be mentioned before getting into the strategies. If you study Freud's model of the mind, you'll discover the Psychic Apparatus. It's the three-part construct in your mind that controls all of your behavior.
