Your newsletter is all yours. Unlike with social media websites like Pinterest and Facebook, your newsletter and email subscribers are all yours, and you have their undivided attention. You don't have to worry about some social media algorithm not showing your content to your readers, as they are your email subscribers so you aren't fighting with anyone else to have them see your content.
Consider a free blogging service. Many people opt to create a free blog using popular services such as WordPress.com or Google Blogger. This is a good option for people who aren't familiar with web design, don't want to pay for their own hosting, or enjoy the ease and stability that comes with these services. These services do have limitations on how you can make money using them, however, so make sure your blog won't break the terms of service.
Advertising is easy to start, making it a popular income stream for many bloggers. However, it’s not nearly as lucrative as it once was and it requires a lot of traffic to be truly profitable. Also, it runs the risk of frustrating your readers (ever been on a site only to be assaulted by the ads?) and making your site look cheap and unsophisticated. Therefore, it’s not a top recommendation of mine.
Once you setup your account on AdSense you will be given a code to add to your blog. This code will automatically display advertisements on your blog from companies who are part of Google’s advertising network. You may see ads from small companies related to your topic, or you may see ads from large companies that are completely unrelated to your topic.
