Going viral on Twitter means that a lot of people are talking about something by sharing posts and tweets (text, photo, video) about that something. To do this, you need to create an interesting post that will capture people's attention and want them to share it with their friends. Make sure to use hashtags that are popular and trending so more people can find your post. Also think about using visual content, like videos and photos, since those tend to be shareable. Finally, talk to other influencers in your industry or the topic of your post to help spread the word.
