Post is the simplest form of content created by a user’s profile and broadcast to an audience. It can be any post you have shared on your social media page or profile. A post can be a few textual sentences, images, videos, or links to any other content. The audience can like, comment, and share the post.
You can share completely different posts on every social media network. Uploading a post does not require much effort, as it should only represent a piece of content that can be easily published on a social media network. The most famous mediums to post on social media are Facebook, Instagram, Twitter, and LinkedIn.
