In the world of sports blogging, there are a few things that are constant: passion, writing skill, and an online presence. With these three things in mind, it is not difficult to see that a sports blog can make a lot of money.
For example, if you have a blog that covers one or more professional sports teams, you can make money by selling advertising space on your website or through sponsorships. If you have a blog that is focused on fantasy sports, you can make money by charging people to subscribe to your email list and by selling products related to fantasy sports.
If you have a blog that is focused on general sports news and information, you can make money by selling ad space on your website or through sponsorships. You can also sell e-books or merchandise related to your blog.
Finally, if your blog has a large following of people who visit it regularly, you can make money by charging people for access to your content (through subscriptions or pay-per-view models).
