There are different ways of posting on Reddit. This also depends on whether you are using the Reddit mobile app or you are using a particular browser on your desktop.
1. To post on Reddit using any browser on your desktop, the first thing you should do is to navigate to https://www.reddit.com/. If you have an existing account on the website, you will be logged indirectly, but if otherwise, you will need to sign in before you can see the Reddit hot page.
2. Look at the upper-left area of the Reddit page, click on the home tab. A list of options will be displayed on the right side of the page, then select a post type.
3. Put the title of the post inside the text box.
4. Decide if you are posting using "Your Profile" Box or through a subReddit box.
5. Create your post, then scroll down to confirm that you are not a robot.
6. Finally, click submit.
