1. Publish to your own publication. This involves creating your own Medium publiucation page that can be focused on whatever topic you want. You then craft content that will specifically be published on that page. This is the easiest way to get published right away.
2. Submit to other publications. This is when you write an article in the hopes of getting it published in another Medium blog. While this is a good way to tap into an established publication’s audience, it does mean you need to write an entire article beforehand with no guarantee that it’ll get published in the publication. Note, however, that if you do NOT get accepted into a publication, you can still put your article on your own page or publication you run.
