I wouldn't say that it's that different from other forms of social media, however what's neat about it is that you don't need a good following for your post to gain traction. You can check out the lewdgames sub's top posts or creators (for example u/timeWizardStudios who tends to post memes about their game or u/kodragon1997 who posts features/snippets) for inspiration. You should also post to multiple communities to maximize exposure.
