Summarize this article:

You should, in some way, let the reader know that your paper is a rhetorical analysis.  By letting the reader know that your paper is a rhetorical analysis, you let him or her know exactly what to expect. If you do not let the reader know this information beforehand, he or she may expect to read an evaluative argument instead. Do not simply state, "This paper is a rhetorical analysis." Weave the information into the introduction as naturally as possible. Note that this may not be necessary if you are writing a rhetorical analysis for an assignment that specifically calls for a rhetorical analysis. Clearly identify the text or document you plan to analyze in your paper. The introduction is a good place to give a quick summary of the document. Keep it quick, though. Save the majority of the details for your body paragraphs, since most of the details will be used in defending your analysis. Mention the speaker, occasion, audience, purpose, and subject of the text. You do not necessarily need to mention these details in this order. Include the details in a matter that makes sense and flows naturally within your introductory paragraph. The thesis statement is the key to a successful introduction and provides a sense of focus for the rest of the essay. There are several ways to state your intentions for the essay.  Try stating which rhetorical techniques the writer uses in order to move people toward his or her desired purpose. Analyze how well these techniques accomplish this goal. Consider narrowing the focus of your essay. Choose one or two design aspects that are complex enough to spend an entire essay analyzing. Think about making an original argument. If your analysis leads you to make a certain argument about the text, focus your thesis and essay around that argument and provide support for it throughout the body of your paper. Try to focus on using words such as "effective" or "ineffective" when composing your thesis, rather than "good" or "bad." You want to avoid seeming like you are passing value judgments.
Identify your own purpose. State the text being analyzed. Briefly mention the SOAPS. Specify a thesis statement.
