You could write a good essay by having a very strong introduction, stating what your topic is about, why it is important to readers or society (it's relivance) Your thesis statement ( your opinion), and also rember to NEVER plagarize, never use information online without giving the author of the article credit, use relevant evidence, have a very string concluding sentence and ALWAYS have a strong counter claim, ( why the opposing side is wrong) and state why they are wrong, your basically trying to persuade the readers into them thinking about your opinion and why your correct.
