There are also other techniques that will drive more engagement to your posts. Including video or images has proven to increase engagement on posts. Also get to your point right up front in your posts. Consider including a call to action such as a question or a request that a post be shared with others, but be aware that generally speaking a single call to action will outperform multiple.
Also use concise sentences, and short paragraphs. Break up longer posts with either numbered or bullet lists. Review posts by highly influential people, and pay attention to their formatting. You’ll also notice that it’s often a good idea to mention a person in a post by adding a + before their name.
