Are your headings clearly defined and used consistently?
You’re writing a report to be designed and published, and your blocks of text need some separation from each other. You write about different things, and headings will introduce the reader to the paragraphs under them. For someone just leafing through your report, they’ll easily spot points of interest and draw them into the text. In a larger text, you might need several levels of headings. The first one is for the general theme, like a chapter title. The next one is for subheadings, for themes within the chapter. The third, and perhaps even the fourth and fifth, for examples or even deeper sectioning. STRUCTURALLY, you should look over your heading hierarchy and make sure it makes sense. Are you using the same level of heading for the same type of content beneath it? TECHNICALLY, you should define the heading with a style in your document, not just mark it and make it bigger. Using heading styles will make it clear to a designer and typesetter what level of heading you’re intending to use. Even though your Word, Pages or Google document’s headings look a certain way, it doesn’t mean it’s the way they will be formatted in the final published document. That depends on brand guidelines, design choices, opinions and technology. There are many ways to make sure headings are clearly differentiated from the normal paragraph style: They can be bigger. Obviously. THEY CAN BE IN ALL CAPS, or small caps (preferably with some good tracking between the letters). They can be bold, italic, underlined (please don’t) – or even combinations of these (oh, please don’t). They can be set in another typeface. They can be centred above the paragraphs, or indented, or outdented, or placed in the margin, or somehow moved out from the expected reading rhythm. They can be coloured, decorated or otherwise made to look different from the main typeface. Or various combinations of the above conventions can make the headings stand out. Just be consistent, so it’s easy for the reader to get that we’re moving on to another topic, or diving further down into the current one.
