Research Your Topic and Take a Stance
Choose your topic and the stance you will take. Make sure you are certain you agree with the opinion you are presenting. If you are not comfortable with the argument you are making, your essay will lose its editorial value.
Without being forceful, present your essay in a persuasive way. You want to reveal your opinion and your understanding of the subject in order to increase your audience's knowledge of the issue.
Research your argument thoroughly. Find information to support your point. Without adequate research, the essay will be merely opinionated, not editorial.
Research your counterargument thoroughly. By researching the opposite stance, you will see what roadblocks your argument faces. Expect readers to hold opposite opinions. It will be the goal of your essay to show them different perspectives and possibly convince them that yours is the best.
Figure out how to weaken the opposing argument in order to strengthen your argument. You can integrate this information into the body of your essay or simply use the information to validate key points.
Outline your important points. An editorial stance must be supported by valid information, evidence and research. Figure out what points you want to discuss and which ones are most important, based on the research you found while looking at all sides of the argument.
Be specific in your points. Make sure to clarify what you are saying and how each point supports your main argument.
Writing the Essay
Write your introduction in a concise way that explains what you mean to convey in the essay. Remember to stylize your argument so that it sticks out to the reader. A dry introduction will lose the audience's attention, so make sure to grab them from the beginning and convince them throughout the essay.
Write the body of your essay. The body will contain your supporting evidence. Outline your points according to importance. Decide whether your argument works best in a pyramid format (most important to least important) or in a logical order. Sometimes it is best to present an argument in the same way your thought process works. Start with a key point of interest and divert the reader's attention to more evidence and other points in a logical manner.
Style is also of key importance. If your writing style grabbed your reader's attention in the beginning, make sure to keep it consistent throughout the entire essay.
Write your conclusion. The conclusion should reiterate your introduction as well as summarize your final points. Make sure to include your strongest argument here again, so that the reader is left with the strongest point as her last thought.
Choose an appropriate title. Some people like to write a title at the beginning, but it is usually best to rewrite it after you have finished the entire essay. It should be no longer than 10 words and should correspond to the content of your essay. Sometimes it is easiest to pick one of your favorite sentences, paragraphs or arguments to construct an effective title.
