 - Essays may compare two subjects or contrast two subjects but most often do both.
 
 - Shorter papers may use a subject-by-subject structure with little risk of disorienting the reader.
 
  - Longer papers tend to use a point-by-point structure so the reader is not obliged to navigate between pages to understand the arguments being made.
 
  - Transition paragraphs are necessary to guide readers when moving from one subject to another.
 
  - Topic sentences begin each paragraph and limit the scope of  what is discussed to one topic within specific terms and should directly relate to the thesis of the essay.
 
  - Subjects to be comparable must have a logical basis for comparison and contrast.
 
  - Subjects must be compared and contrasted by identical terms and and should be based on the same criteria or categories.
 
  - The results of a comparison and contrast should be non-trivial.
