Keep your similar information together. When describing your evidence for example, keep your evidence in the same parts of your paper. Do not let yourself get distracted off of some other tangents in a new paragraph and then return to your evidence in a third. If you have one piece of evidence/example that flows from into another, all the better to put those paragraphs next to each other.
A personal example of the above is when I wrote a paper about High Fructose Corn Syrup, two pieces of evidence I used were about how they messed up with two separate digestive processes. Since they were both about the dangers and about digestion, I could have one paragraph about how HFCS not only subdued your feelings of how full you are into a second one about how HFCS reduced digestive enzymes.
