Many people make money online by starting a blog or website on topics that interest them. It could be sewing, knitting, basketball, travel, board games, writing, or whatever else may interest you. Then you begin to do an outline of how you will design your site into pages sorted by relevant keywords that are associated with your keyed interest. Once that is established you begin writing and writing and writing. It won't feel like a job because it interests you. Then you link to other relevant websites associated with your niche. This may take some work and why it is important that you write about your topic well or have an established writer do it. Then you will see traffic coming in after you backlink, submit to search engines, directories, etc. . Then you can link to affiliate products associated with your site and/or ads that earn you a significant income. The more traffic you receive, the more income you get.
