Find a topic or person to satirize. Be up to date on current affairs, both local and national. Chose the subject wisely, making sure the issue is something of great importance to you. Fact-check your information by checking multiple reputable sources and make sure the information is up to date.
Make sure your criticism of a particular subject is valid and the subject is put into focus. Also, determine your writing style and voice in your piece. Go for the ideal style, which is literary, sly, under-handed and trenchant. Do not be outwardly insulting or obscene, as such shock value will detract from good satire. The Bandersnatch website, a publication specializing in satire, uses the term "delightfully vicious" in describing the ideal satire writing style.
Know your intended audience. Be certain that readers know what you are satirizing. If you plan to parody a person by substituting the name in the piece, for instance, it should be immediately obvious whom you are actually satirizing by your descriptions.
Choose an eye-catching title and picture. Use a clever title that will immediately let the reader know that it is a satire. Also, use a good picture of your intended subject to accompany the article. If the piece is for a newspaper, the picture might be provided for you by the editor.
Make sure to frame the piece within proper context. Publish the article in a literary journal known for scathing humor or in a newspaper column especially for editorials or satire pieces, as opposed to putting the piece in a very serious newspaper or journal. If the piece is placed in a very serious context, it will catch the reader by surprise and the humor will likely get lost.
