As well as selling your eBooks, Amazon can also create paperback copies of your book. CreateSpace, an Amazon-owned company, will help you self-publish your book. A relatively straightforward process, you must upload your work to CreateSpace and submit it for review. Your book will then be displayed on Amazon, and printed on demand and shipped by CreateSpace when purchased. And you can collect up to 70% royalties for each book sold.
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. And by far, the best webinar platform out there is certainly GoToWebinar. Hands down, there isn't even another platform that comes close.
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
