Simple posts on LinkedIn go viral because they are easy to read and people find it easy to comment on them. The main reason for this is to generate interest and engagement in the post. LinkedIn's algorithm gives the most importance to comments and people immediately comment on simple and easy posts, while people scroll forward after reading longer posts. Therefore, LinkedIn's algorithm also shows the post at the top that is getting more likes and comments. If you want your post to perform well, keep your post simple. A good post is one that teaches people something and also invites them to participate in the conversation.
