How to use headings effectively

Headings are the skeleton of a piece. They show the reader — and the search engine — what each section is about, and they tell a skimmer whether your piece is worth their time.

What they are

Headings are titles for the sections of your content. A single H1 heads the piece, H2 heads the main sections, and H3 heads subsections within them. They are a hierarchy, not formatting for its own sake.

Why they matter

Readers scan, especially online. Headings let them find the section they need and judge the content at a glance. They also help search engines understand structure, which is good for content you want found.

How to use them

Use one H1 only. That is the title of the piece. Only the main heading should be H1; every other heading is a level below.

Use H2 for the main sections. Each H2 should introduce a distinct part of the piece. This is where your outline becomes visible.

Use H3 for subsections. When a section has several points, split them with H3. Do not skip a level (H2 to H4) — it confuses the hierarchy.

Make headings descriptive and useful. A heading should tell the reader what the section covers. "How to choose the right market" beats "More tips." Descriptive headings help both skimming and search.

Keep headings parallel and short. Use a consistent form (question, phrase, or command). Keep them short enough to scan.

Match heading to section. If a heading says one thing and the section says another, fix one. A mismatch is confusing to readers and search engines.

Headings and length

Not every piece needs headings. A short email or a brief note does not. Long articles, guides, reports, and blog posts benefit from headings to break content into readable chunks.

Common mistakes

Using several H1s. Using headings for style (making things bold or big) instead of structure. Skipping levels. Vague headings like "Info" or "Tips." Headings that do not match their content. Bold paragraphs used instead of real headings.

Practical tips

• Write your outline as headings, then fill in each.
• Turn each heading into a stated benefit or question.
• Check that a reader skimming only your headings gets the gist.

Checklist

• I have one H1 for the title.
• H2s mark the main sections.
• H3s mark subsections and nothing is skipped.
• Headings are descriptive and match their content.
• Headings are parallel and short.
• Skimming the headings conveys the structure.
