Before I open an article, I want to know more than its subject. I want a quick sense of what it will explain, where it will go, and whether it reaches the question I came with.
Headings Should Show Progress
An outline works when its headings describe the steps of the article, not just repeat the topic in different words. A post about choosing a reading routine, for example, might move from finding a realistic time to deciding what to read and making the habit stick.
That sequence gives readers a sense of the article’s shape before they commit. Vague headings such as “Getting Started” or “More to Consider” offer little guidance on their own.
Keep the Preview Concise
A preview should make the structure visible without becoming a second version of the post. A short outline, paired with a concise summary, can signal the key points while leaving the explanation and examples for the full article.
If every minor detail appears in the preview, the main idea gets harder to see. Choose the few sections that best show what readers will take away.
Make the Promise Match
The most useful outline is an accurate one. If a heading promises a comparison, the article should compare; if it promises a practical method, readers should find steps they can actually use. A clear preview helps people choose, and the complete post should deliver on that choice.
