Another way you can share your knowledge with the world is with a blog dedicated to your area of expertise. Bloggers typically earn money by placing ads on the site.
The most popular way to do this is with Google AdSense — you decide where on the page you want the ads to appear and Google AdSense will match the content of your blog with advertisers looking for readers like yours.
Another way to make money blogging is by placing affiliate marketing links on your posts. With affiliate links, the URL has a unique code attached to it. When readers click on the link and make a purchase, you receive a commission.
Creating a blog doesn’t have to be difficult. Sites like WordPress, Squarespace and Wix can help you quickly create an attractive and easy-to-navigate website with integrated ads.
