That depends on what kind of essay we are talking about. If you are talking about a persuasive essay, then use different appeals and techniques, like ethos, logos,pathos, facts and figures, or testimonial. If we're talking about a narrative essay, then use plenty of imagery and sensory details, plus make sure to have plenty of characterization for your dynamic characters.
