Manually posting the same post on several subreddits can be a hassle. Crossposting takes that hassle away by allowing you to post in one subreddit and then share across several others. If you’re new to crossposting on Reddit, here’s how to use the feature.
What You Should Know About Crossposting on Reddit
Crossposting allows you to share a post from one subreddit to another subreddit without having to create a new post. This way, you’re able to reach more people and spark more discussion on your post.
However, crossposting is not allowed everywhere. Some communities may disable the crosspost feature or have specific rules about what kind of content can be crossposted. You also need to be a member of a community before you can crosspost there. Therefore, before you crosspost anything, make sure you check the community’s rules and guidelines and respect their preferences.

Another thing to note is that crossposting should be done sparingly and selectively.Good Reddit etiquettedemands that you don’t spam multiple communities with the same content or post irrelevant content that doesn’t fit the theme of the community. This can annoy other users and moderators and may result in your posts being removed or your account being banned.
Crossposting should be used as a way to share interesting, useful, or relevant content with other communities that might appreciate it, not as a way to farm karma or promote yourself. Crossposting relevant content couldincrease your chances of hitting the top page on Reddit.
